Is my blue your blue? (2024)
- bojo 5mo agoWhile neat, I don't get consistent scores if I retry it a few times. If it leads with a series of greens first, my score is more green oriented, and vice versa.
- engineer_22 5mo agoIs this a test of perception or a test of how humans make choices
- rendx 5mo ago> Your boundary is at hue 174, just like the population median. You're a true neutral.
- smokedetector1 5mo agoThe other week my wife and I were disagreeing over whether a house was green or blue. I was shocked when every passerby we asked agreed with her that it was green. I was absolutely 100% sure it was blue. Turns out according to this site, my boundary is greener than 95% of the population! Funny to see this proved out here!
- rnewme 5mo agoSame situation happened to me, and I have same test result as you.
- VadimPR 5mo agoI had the same discussion with the color of a river in Albania with my wife. The test says my boundary is a bluer than 85% of the pop - sounds about right!
- bitexploder 5mo agoI am bluer than 78%. Colors. How do they work.
- strangegecko 5mo agoI'm bluer than 98% apparently. For me, turquoise is green. I didn't realize that's not normal. If I'm off on a detail like that, then...uh oh.
- tetris11 5mo agoblue than 90%, same verdict with turqouise, though what I call turquoise is bluer than what is shown

- makr17 5mo agoIn the sitcom Mad About You there is an episode where Jamie tells Paul to put on a tie. Specifies the "navy blue one". "I don't own a navy tie." "Yes you do, it's the one that you think is dark green." My wife and I go round and round about what is and isn't blue and/or green.
- a_shoeboy 5mo agoI have had similar conversations with my wife a few times, but I'm the one with working color vision.
- PunchyHamster 5mo agoBut navy blue is just dark blue
- cpburns2009 5mo agoYeah that scene doesn't make any sense. A dark teal that could be confused between blue or green would look nothing like navy blue.
- miriam_catira 5mo ago...I get different numbers depending on which eye I use, but both are fairly center. I didn't expect blue-green to be affected though! My left eye can't see certain shades of red as well as my right eye. Bright sunlight makes it more noticeable, but my own skin looks weirdly (sickly) yellowish with one eye and normal with the other. Whenever it's come up at home, my spouse simply insists "I don't need to know the difference between aqua, turquoise, and seafoam. They're all blue." At this point I just nod and agree, it's not worth the fight anymore. ;)
- pleurotus 5mo ago...I never found another person with the same experience. Here we are. For me though, it's not that sunlight makes it more noticeable, it's that I will see the same shades until I've had too much sunlight—eventually my left eye gets tired, I guess, and sees a lot less red than my right eye. After sleeping it resets and I see the same shade in both eyes. Maybe i should talk to a researcher about this..
- abelitoo 5mo agoI realized at a young age that one of my eyes receives a more blue-shifted image and the other's image is more red. It's difficult to tell by rapidly opening/closing one eye at a time, but by using my fist positioned with my thumb resting on my brow between my eyes, then rolling it left and right quickly to cover up one eye and focusing on what I'm looking at, it's a stark difference. I do it every so often to see if it's changed with age.. I especially enjoy looking at the sky or white sheets of paper.
- TZubiri 5mo agoI have this with a coat, but it's blue vs gray. Would be interesting to generalize this tool not just for other colours, but for other colour properties like saturation not just hue.
- armada651 5mo agoMany languages considered green and blue so closely related that they grouped them together under a single term: https://en.wikipedia.org/wiki/Blue%E2%80%93green_distinction_in_language https://en.wikipedia.org/wiki/Blue%E2%80%93green_distinction...

- javawizard 5mo agoIt's better than bleen I suppose. Speaking of, I'd be curious about a similar experiment but one that compares how grotesque, for lack of a better word, certain words sound. The word bleen makes me uncomfortable, I think because my brain automatically goes to spleen; grue isn't my favorite either but I prefer it to bleen. I'm curious how universal that is though. Do others have similarly aligned preferences for one word over the other, or are our feelings about them more evenly spread?
- martheen 5mo agoNot a native speaker, bleen for me got auto corrected by my brain to green. It doesn't make me uncomfortable, but I'd prefer grue because my brain will immediately understand we're talking about the umbrella term. If grue is said out of context, I'd imagine Gru from despicable me, when written I'd imagine gruel, but, again, because I'm not a native speaker, instead of yucky food I'd instead think about that episode of Masha and the Bear where they end up with a houseful of the porridge.
- Crpt774 5mo agoThis one in particular is going to be difficult to get good results. Depending on your era you may have been eaten by a grue at some point.

- rubslopes 5mo ago90% here, and it makes sense. I'm very picky about saying something is blue!
- raddan 5mo agoThat’s amusing because I am the converse: my boundary is bluer than 98% of the population. To a first approximation, blue is a very specific thing and all the other colors appear strongly non-blue to me. I do wonder where this preference came from, but it explains all the puzzling interactions between my wife and I over the years.
- smokedetector1 5mo agoThat's fascinating. I think this has to be biological. When I call something blue I don't think it has to do with just what I've learned but also that the color feels more like deep blue than it does like deep green.
- a_cardboard_box 5mo agoMy boundary is also greener than 95% of the population. I think it's because I mentally separate cyan from green and blue, but still see cyan as a shade of blue. If you asked me what color it was without forcing green or blue, I'd have answered cyan on most of them.
- percentcer 5mo agoI think the alternative should be "this is not blue". I was served what I would call a "teal" or "turquoise" but the alternative button shows "this is green", which it was not.
- StilesCrisis 5mo agoI totally agree with you but it defeats the purpose of the site. It got to an obviously cyan color and I couldn't answer either way (it's not blue or green) so I closed it.
- jedmeyers 5mo agoSame here, it's often neither blue nor green, so this experiment is pointless.
- ajkjk 5mo agoI closed it also. What's going to happen is all the people who care about the ambiguousness leave, so the resulting population is a bad sample even of the people who open the site in the first place.
- SunshineTheCat 5mo ago100%. It's like being asked is this black or white and being shown 50% grey.
- reactordev 5mo agoThat’s the point of this. To find out where in that spectrum your vision lands, not to get a perfect score.
- xmprt 5mo agoOP's point is that this isn't valid because neither of the answers are correct. If you're really trying to measure a spectrum then the answers should allow for fuzziness. That is, you have a range/confidence interval of where green ends and where blue starts and in between is neither/both.
- HoldOnAMinute 5mo ago>> Your boundary is at hue 177, bluer than 76% of the population. For you, turquoise is green. Not really sure how to interpret this. Where is "normal" on the curve?
- rationalist 5mo agoThe About section at the end said most people average around 175.
- dbcurtis 5mo agoIt seems to me there is a broad range of "normal", as in well within the standard spec sheet tolerances for humans. It is more about what is average or median.
- diziet 5mo agoThere are colors in between blue and green that are neither blue nor green!
- lokar 5mo agoAny system of giving names to hues will necessarily use ranges. I think the intent here is clear in context.
- lrobinovitch 5mo agoThis is great! Somewhat similar to a site I made a while ago, but for more "perception boundary" colors: https://theleo.zone/colorcontroversy/ https://theleo.zone/colorcontroversy/
- nubinetwork 5mo agoI must be colourblind, most of those look the same on my phone.
- QuantumNomad_ 5mo agoSame. There were like three different colors at first and then the remainder looked mostly the same. Also, I wonder how the results are affected by my screen and environment. I’m on an iPhone in a dark room, with brightness turned all the way down and I currently have TrueTone enabled and Night Shift enabled. I was bluer than x percent of the median. Night Shift mode reduces blue light exposure. At daytime with Night Shift off, I would surely be seeing the boundary earlier, as there would be more blue light transmitted by my screen. I may have to repeat the attempt multiple times on different screens and lighting conditions (both indoors annd outside) and see if the results vary wildly or not. I think they will.
- dbcurtis 5mo agoWho else tried with both eyes? A few years ago I had an implant to treat cataracts. It was notable at the time that the "new" eye was less yellow-tinted than the aged-in-place eye. I was told that the lens does yellow with age. Over time, my brain mostly adjusted, but on this test I did notice a subtle hue difference between eyes. Did anyone else try that experiment?
- eecc 5mo agoCan you accommodate with the implant?
- dbcurtis 5mo agoNo. I got it set for distance vision. There are modern implants that are "multi-focal". But they work by spreading out the light, so everything is less bright at any distance. My two pieces of anecdata are: 1. A friend with multi-focal implants says that he needs a very bright light for reading now. Which is one of the reasons I avoided multi-focal. 2. My optometrist got multi-focal, and he noted that it required retraining his brain somewhat, because now instead of accommodation providing focus, focus requires mental attention to the subject of interest. Cataract implant technology is moving very fast, and my data is about 5 years old, so YMMV.
- afandian 5mo agoCool to see this experiment crowdsourced. Guy Deutscher’s “Through the Language Glass” is a very readable history of linguistic relativism, including the long history of this experiment. It even has some colour plates to illustrate. Recommended. https://www.penguin.co.uk/books/412264/through-the-language-glass-by-guy-deutscher/9780099505570 https://www.penguin.co.uk/books/412264/through-the-language-...

- rootusrootus 5mo agoAnd what if you are wearing blue blocker readers? I am, and perhaps unsurprisingly my result was greener than average. ETA: But of course when I retook the test without my glasses, I went even greener.
- beejiu 5mo agoI got a 98-percentile result and realised my Mac had Night Shift turned on.
- TZubiri 5mo agoMaybe both are true, if someone grows up and learns through a specific monitor, maybe that will influence and define their blue definition.
- kraai 5mo agoYes, this test only works somewhat if you have multiple people use the same monitor/screen. Otherwise it's mostly useless for accuracy.
- NetMageSCW 5mo agoAll iPhones are calibrated.
- hyperpape 5mo agoI think this site is doing a binary search, so that you narrow down on a boundary. It would be much funnier, and also more insightful, if it didn't do this and let you contradict yourself.
- aaronharnly 5mo agoYeah, as I was toggling "blue" / "green" / "blue" / "green" I had the distinct sensation that it might just show me that I was in a region where I couldn't even make a consistent distinction.
- benleejamin 5mo agoI think there's an anchoring effect in play here. If you select blue -> blue -> green -> blue -> green -> blue -> green…, you land at the population median. (The point being that, once you get to a somewhat ambiguous point (after two blue selections), you can say "oh, well, compared to the last one this is {opposite color}!", and it seems most people do that.)
- layer8 5mo agoThat doesn’t explain why I landed 92% off the population median.
- make3 5mo agoit's a binary search, not too surprising. search over a unidimensional ordered space
- make3 5mo agothis made no sense btw, this would give 4/3
- djmips 5mo agoMy boundary was hue 188, bluer than 98% of the population, for me turquoise is green and then it shows an overall chart which I have to agree with so no, I don't agree with your assessment. I often get into blue/green arguments with my children and that's when I started to suspect that it was personal opinion.
- muzani 5mo agoThat's if you're matching about 40% of the population. For some, it might be blue -> blue -> blue -> blue -> green -> blue -> green -> blue.
- burkaman 5mo agoI wouldn't assume most people do that. For me the last few looked basically the same so I selected the same color for all of them.
- timnetworks 5mo ago> Your boundary is at hue 172, greener than 63% of the population. For you, turquoise is blue. isn't turquoise exactly (50%) between the two?
- chao- 5mo agoThe "exact 50%", or the boundary between green and blue, is nominally hue 180, which is cyan. A search for the RGB, CMYK and HSL for turquoise yielded a few hue values from 171 to 174 (depending who you trust, and allowing for a bit of drift due to colorspace conversions). In any case, 171, 172, 173, and 174 are all on the green side of cyan.
- gkhartman 5mo agoHow much does display calibration factor into this? I'm fairly confident it must impact the results, but unsure how much error it would introduce.
- AntiUSAbah 5mo agoI always wanted to have a color calibrator and a few years back i bought one. all my displays were so well defined out of the box, it wasnot worth it at all. Like you would need to use this particular profile for proper real industry printers to even have any benefit of it if even because all my displays were well calibrated. I would argue that this would only make sense for highly profesional graphics designer and i don't think this experiment requires this level of granularity.
- swiftcoder 5mo agoA lot of the color calibration obsession was from back when panels shipped with truly awful factory calibration. A quick perusal of rtings suggests that most manufacturers try and pre-calibrate their panels these days
- nomel 5mo agoAmbient light color would play a bigger part, with modern displays being fairly good.
- nomel 5mo agoRelated, here's a nice collection of measurements: https://www.displaymate.com/mobile.html https://www.displaymate.com/mobile.html The last few generations of most everything have been rated "Visually Indistinguishable From Perfect", so it seems they don't test as much anymore.
- MrZander 5mo agoInteresting. Looking at each in isolation, my boundary is pretty far into Green territory. But when I look at the gradient, I would place it far closer to the center. Also, I found that sometimes it looked like there were two colors. The top was green and bottom was blue. Maybe my monitor?
- nicebyte 5mo agoit's a neat experiment but I think it's ultimately flawed because color is usually perceived in context, and depending on context I could easily see anyone reinterpreting the hues they labeled "green" in this test as blue, and vice versa. EDIT: in general, blue is a pretty fascinating color. yes, many cultures have a somewhat blurry distinction between blue and green. Some others seem to differentiate shades of blue that others don't (i.e. in Russian "голубой" and "синий" refer to distinct colors but in English those would be just shades of blue). I guess there's something about photons in that energy band that messes with perception. https://en.wikipedia.org/wiki/Non-photo_blue https://en.wikipedia.org/wiki/Non-photo_blue
- analog8374 5mo agowe used to not have a word for orange. we called it yellow red. then this new fruit arrived from India
- seemaze 5mo agoThis makes no sense. It's like asking: "Alice is in Denver. Is Alice in (a) Canada or (b) Mexico?" - Your boundary between Canada and Mexico is at 40° latitude, more southern than 53% of the population.
- phaedrus 5mo agoSomeone should make a parody site asking whether shades of yellow are red or violet.
- miltonlost 5mo agoYour example would only be valid if "blue" and "green" had objective answers for when something is Blue and something is Green and have clear demarcated boundaries. You're switching to a literal boundary example where there are actual lines to be crossed. Colors are a fuzzy continuum; national boundaries, not including fought-over areas like the Sea of Japan, are easy to be in or not.
- Rapzid 5mo ago> Colors are a fuzzy continuum Denver is teal, the USA blue-green. Canada is Blue, and Mexico is green. Their analogy is pretty on point.
- TZubiri 5mo agoYou are confusing geographical position with countries. Countries are not a continuum, they start and end at some specific line defined by constitutions, mutually agreed by neighbours (or disputed through war and diplomacy) Colours have no such incentive for strict unified definitions, so there is no point at which blue ends.
- Rapzid 5mo agoI'm not confusing anything. I am 1000% unconfused and entirely on the same wavelength as OP. You're inability to wrap your head around the analogy is tantamount to.. Not being able to comprehend blue-green.
- wat10000 5mo agoI wonder how much of this is testing people's eyes/brains, and how much is testing their screens.

- sega_sai 5mo agoOne thing that I find interesting when thinking about colour perception, is that even if two people agree that a given colour is red, there is no way to know (as far as I am aware) that they actually perceive it in the same way. Maybe the brain of one person paints it red, and another paints it differently, and there is no way to know as we can't get into other people's heads.
- VadimPR 5mo agoI find that fascinating as well! I hope tech will give us the answer in our lifetimes.
- keane 5mo agoQuite right: https://en.wikipedia.org/wiki/Qualia https://en.wikipedia.org/wiki/Qualia
- rootusrootus 5mo agoyep, this is the sort of question I pose to my kids. “How can you know that what you see as blue is not what I see as red?”
- shagie 5mo agoI've got an anecdote that says that they don't. If I'm looking at a certain color of green illumination and then cover one eye then the other, my perception of that color shifts slightly. It's still green, but with one eye it is "brighter" than the other eye.
- layer8 5mo agoThat’s assuming that there is something like a “true” internal color that external colors are mapped onto. I think it’s more likely that for the brain, “red” is just “that hue signal range that red things have”. Which is roughly the same for everyone (modulo color blindness), in the sense that if one person sees two objects as red, another person will also see them as the same color, and will perceive the same brightness and hue relation relative to other objects with adjacent brightness and/or hue. Meaning, there is no absolute color, the brain just learns what things have the same color, and how similar or dissimilar they are in hue to other objects. And for example “cold” colors are cold because we associate them with cold things, not because of some independent “qualia”.
- nox21125 5mo ago>> Your boundary is at hue 173, greener than 57% of the population. For you, turquoise is blue. very subtle changes in color after the first two. it also seems to be repeating blue -> green -> blue -> green, for me atleast.
- jameson 5mo ago"teal" is the name for color "Moderate bluish green" https://en.wikipedia.org/wiki/Teal https://en.wikipedia.org/wiki/Teal
- chao- 5mo agoYes, and since Teal is Cyan with 50% Value, you will often also see people use Cyan to refer to the boundary color between Blue and Green.

- wilj 5mo agoThis is awesome! I have a slight case of tritanopia in one eye and it was neat to see the difference. My boundary is bluer by 59% in one eye and 87% in the other. It tracks with what I would have expected.
- dueltmp_yufsy 5mo agoI was always fascinated by this kind of question as a kid. Like I would imagine that everyone had all the colors mixed up and we were each seeing something different.
- red75prime 5mo agoI forgot that my display is in night mode (reducing blue light intensity). And I ended up with "your boundary is bluer than 98% of the population."
- moffkalast 5mo agoThis is cyan!
- layer8 5mo agoThis only checks a single brightness level per hue. I bet that two people who agree for those levels might very well disagree at other levels, and vice versa.
- harrall 5mo agoOne of my eyes sees (very) slightly greener than the other one. But with both eyes I got > Your boundary is at hue 174, just like the population median. You're a true neutral. I should test with one eye.
- B5C8ECB24DB47D1 5mo agoSame here. 'My blue is not my blue', or yellow in my case. I realized this looking at the yellow doublet lines from Sodium vapor lamps: one of my eyes sees it greener than the other.
- deleted 5mo ago[deleted]
- zuminator 5mo agoWhen the final threshold image was displayed, I felt that the boundary was too far over to the left and I had a fair amount of green on the blue side. I think this would work better if the hues jumped around a bit instead of blatantly triangulating, so that you wouldn't be biased by your prior semection.
- iterateoften 5mo agoIm left delighted to find out something new, but left wanting to know how to use it. Like if im 75% on the green transition, how do i use this information.
- glial 5mo agoSend it to a significant other, then discuss your differences. Will provide you with a new in-joke.
- mbo 5mo agoI feel like there needs to be some sort of intermediate black screen between the questions, a visual "palette cleanser" if you will. I was actively noticing the saturation of the color decline as I stared at the screen.
- porphyra 5mo agoThere's a big cultural component to it, and many languages don't even distinguish blue and green! Also many languages only distinguish them surprisingly recently --- for example, Chinese and Japanese used to use the word 青 which can refer to both blue and green, and even now, the color of the sky in the Republic of China (Taiwanese) flag is referred to by that character. https://en.wikipedia.org/wiki/Blue%E2%80%93green_distinction_in_language https://en.wikipedia.org/wiki/Blue%E2%80%93green_distinction... https://en.wikipedia.org/wiki/Blue_Sky_with_a_White_Sun https://en.wikipedia.org/wiki/Blue_Sky_with_a_White_Sun
- keane 5mo agoSame with Old and Middle Irish (1200 AD): "glas was a blanket term for colors ranging from green to blue to various shades of gray" I like to think this may have had something to do with them having both blue and green in their political usage: https://en.wikipedia.org/wiki/St._Patrick%27s_blue https://en.wikipedia.org/wiki/St._Patrick%27s_blue
- balupton 5mo agoSame applies for grey, and many other colours and things. For Indonesian culture, grey is the colour of an overcast/hazy/dusty/ash/pale day, as such, it includes any desaturated colour, especially (most commonly) light blues; so for them two blue banknotes, one saturated and one desaturated are clearly different colours and they are perplexed as to why westerners mix them up. More research of this <https://en.wikipedia.org/wiki/Basic_Color_Terms https://en.wikipedia.org/wiki/Basic_Color_Terms>. From my research, a lot of this comes from whether a culture's consideration of a colour is from natural phenomena, or from colour theory (mixing the primary colours to generate the secondary colours, developing color wheels, acquiring distinctions for hue, saturation, lightness, etc). Take "orange" in English, or "cokelat" (the colour brown, and chocolate) and "oranye" (to describe the colour of a ripe orange/"jeruk manis") in Indonesia. Sometimes with cross-cultural intermixing, an object could be named after a colour in one culture, then that object is injected into another culture, and that culture then names the colour after that object. Such cultural introductions also extends to mythology and affect, lighter shades could be considered young or easy (as is "muda" in Indonesian), white could be considered for pure or wealthy or sickly or light, dark for ground/earth or peasant or tanned/healthy, red for blood/danger or passion or love; blue-green for nausea or life/vitality/fertility; same also applies for gender and pronouns; man as in mankind, or man as in male, and their inter-cultural/educational corruption/degradations/influences/experiential-biases/subjectivity.

- fourthark 5mo agoInteresting, I got a completely different result on green/blue on this one, way more green whereas I got average on the individual test. Going between very different colors makes it hard to reset - they might consider breaks between spectra.

- FarmerPotato 5mo agoThanks to the TMS9918, I know cyan when I see it! Years of seeing cyan on a composite monitor where hue is tricky to adjust. My tolerance for the amount of green allowed in cyan is higher. And if it's cyan, it's blue. I see I classified quite a few greenish as cyan therefore blue.
- antisthenes 5mo agoThis assumes that the person you're testing isn't aware of the whole category of colors that sit between green and blue? There's teal, cyan, aquamarine, etc...It's such a uniquely american notion to force someone to categorize something (incorrectly) into one of 2 things. Almost a comical parallel to the political system.
- ticulatedspline 5mo ago72 green though where it drew me on the gradient at the end I definitely would say the line is on green. and the swatch that is says I think would be blue was, well turquoise and not "blue". my path was basically: ok def blue, ok cyan which would be "blue", greenish sea-foam? teal? ok now I wouldn't call these green Or blue . Then kinda bobbled the guess crappy monitor aside, Feels like there's a combination of factors, some color fatigue from looking at a full screen saturated color and I think some "over thinking" the colors.
- malbs 5mo agoAlso no way to account for the variation of LCD displays. The same "colour" can look different on two different panels
- anyfoo 5mo agoWow. Did anyone else have some serious trouble with this? The first color was obvious to me, as it was designed to be (it even tells you if you intentionally misclick). But at the very next color, the first "test color", I literally face palmed and said "oh my god" out loudly. It was so, so hard for me to decide. I really just wanted to pick a non-existent "teal" option. Both "blue" or "green" felt wrong and equally right at the same time. It just got harder from there. At the end, it told me that my threshold is "bluer than 80% of the population", but honestly, I don't think that's really true in my case. I was so ambivalent, my choices really felt random to me very quickly.
- softbuilder 5mo agoI want this but for blue vs. purple.
- jp57 5mo agoI have my doubts about the value of a two-alternative forced choice task for this. I was pretty much answering randomly both of the time because I wouldn't ncessarily have called either green or blue.

- Rapzid 5mo agoI don't find this compelling as it seems to me it's well acknowledged there are colors that are BOTH. As in there are colors widely considered to be blue-green. Blue and Green.
- danbmil99 5mo agoDunno if this is a late-in-life thing or I was always like this, but I definitely need more blue to see blue than most (this test put me at 82%, I think that means I'm in the lowest quintile for seeing blue?) Bright blue still looks mighty blue, but when light is dim, I basically see black where most would still see blue. Practical ramifications: * Some of my 'black' shirts are blue when it's sunny * Popular desktop themes (solarized dark) have text that is completely unreadable

- carlovalenti 5mo agoI remember a pic of a shirt, which a former colleague of mine was showing on his monitor ten years ago, and the office splitted half in recognizing the colours, can't remember if they were gold vs black; but we went crazy because nobody could believe that the other half was seeing a colour different from the one they were seeing!

- Glyptodon 5mo agoI don't like this because many of these transition colors I don't really consider blue or green but some sort of blue-green or green-blue. I would also trust the results more if it bounced you around a bit randomly rather than tried to center you in. It gets to a point where I don't really have confidence and I suspect the environment around me contributed a fair amount at that point. Seem to get ~172.
- bandofthehawk 5mo agoI feel the same way, after the first couple of responses, I was just thinking it's blue-green. So I just had to pick randomly. A better interface would have been to just show the final spectrum pic and slide to where you think the separation is.
- fwip 5mo agoI suspect that asking people to pick on a visual spectrum would lead to most people clicking closer to the midpoint.
- dc96 5mo agoNoticing on my monitor that it's more blue if I tiptoe and look down, and it's obviously green when looking at below. I think a better way to standardize this without too much variance in color would be make the user denote on the screen where they are actually looking perpendicular to the screen and judge from that area.
- ece 5mo agoI got hue 175 twice, but bluer than 66% of the population once and 59% the second time.
- foxes 5mo agoI just took it to mean is this more blue or green rather than literally blue or green. Correct answer is then 180, anything else is clearly a fail :)
- gumby271 5mo ago"for you, turquoise is blue." Well no, it's turquoise, that's why we gave it a whole different word.
- TZubiri 5mo agoBut turquoise can be a blue, just because we have a specific word, doesn't mean more general words are invalieated or made as specific. For example, things can be small or big, a mouse is small, if you refine the vocabulary to include 10 size words, and the mouse is now minuscule, it is still small.
- philipwhiuk 5mo agoFor many people this is like saying 'for you red is blue'.
- TZubiri 5mo agoBut in terms of the physical properties of color, namely wavelength of the photon waves, red is diametrically the opposite of blue, they are literally the most different colors. While turqouise and blue have quite adjacent centers and wider definitions. I get that our subjective definitions can be different, but in this case the subjective differences suggest a difference in objective understanding of color (and countries apparently.)
- muzani 5mo agoThis is the first time I realized that turquoise is the gray area.
- throw0101c 5mo ago> Well no, it's turquoise, that's why we gave it a whole different word. For some people "pink" does not exist as a concept, it is "light red". In English we talk about "light blue", but an Italian may talk about azzurro (galazio (γαλάζιο) in Greek; kachol (כחול) in Hebrew). Is azzurro its own colour different from "blue" for everyone, or only for Italians? Is "pink" a different colour than (light) red? Before the different word of "turquoise" was created, did the colour still exist and/or be perceived? * https://en.wikipedia.org/wiki/Turquoise#Names https://en.wikipedia.org/wiki/Turquoise#Names If a language/culture does not have a word for "blue" does that mean the colour does not exist? * https://en.wikipedia.org/wiki/Basic_Color_Terms https://en.wikipedia.org/wiki/Basic_Color_Terms * https://en.wikipedia.org/wiki/Blue–green_distinction_in_language https://en.wikipedia.org/wiki/Blue–green_distinction_in_lang...

- caymanjim 5mo agoI wouldn't call most of those colors green or blue. Most of them looked identical to me as well. I ended up picking arbitrarily for all but the two I thought were distinctly one or the other.

- aleph401 5mo agoIn Japanese, the "go" traffic light is referred to as "blue."
- WesleyJohnson 5mo agoI'm sure this isn't an original thought, but I wonder how others see colors. Irrespective of color blindness, is what I know as red appear as blue to someone else? How would you even know or describe it? "Red, like a strawberry, tomato, or apple." And they say, "Yes, exactly." But what they're truly seeing is what YOU know as blue. They see something different than you do, but to them that color has always been called red - even though, if you were to see it as them, it's blue.
- michaelmior 5mo agoThe scenario you're describing seems like more of a language thing than a perception thing. We generally learn names of colors by references to common objects. I would argue that if people agree something is "Red, like a strawberry, tomato, or apple" then it doesn't really matter what you're seeing, that color is red.
- strogonoff 5mo agoOur experience doesn’t become unimportant just because it’s lost in translation. It’s a paradox that we can’t know what X feels like to another person because communication is very lossy, but that does not warrant dismissal. We are not p-zombies, we do feel things. In fact, the argument that “what we experience doesn’t matter” looks incongruous insofar as it is made by an entity experiencing something and in fact because said entity is experiencing something—the entity has no access to anything but experience.
- michaelmior 5mo agoI'm not saying our experience is unimportant. I'm talking about how we communicate what colors are. I'm not an expert by any means, but it seems like the way we communicate a shared understanding of what colors are is based on observing things that are the same color. I just don't think we have a way of communicating our subjective view of what a color looks like without reference to some other color.
- dc96 5mo ago
- aidenn0 5mo agoJust last week I called something blue and my daughter objected; she said it was green. After discussion we both agreed it was was teal and she said roughly "but teal is a shade of green." To me Teal is a (admittedly greenish) shade of blue.
- LocalH 5mo agoAlso needs a button "this is both" for colors like cyan
- hn_throwaway_99 5mo agoI never understood "forced classification" games like this (as an aside, it's also why I always hated Myers Briggs). Maybe it's because I'm somewhere on the spectrum, but it always seems like a dumb, false choice to me. For example, when I saw the second color, "aqua" immediately popped into my mind. Aqua is literally defined as #00FFFF in RGB color space - no red, equal (max) parts blue and green. So it just felt like flipping a coin to me as it felt neither more blue nor more green.
- martinky24 5mo agoIt's a fun toy website.
- nodompa 5mo agoBut what about the definition of aqua outside of any digital color space? I feel like using only RGB values to define 'aqua' is a bit reductive as it is merely a specification in a specific environment trying to render a type of color but with inherent limitations such as not being able to reproduce the whole spectrum, color accuracy on the display, etc. etc. there's a lot of other parameters along with your own individual color perception that goes beyond "it's equal values blue and green within the RGB color-space" But then as I list all these things I think I arrive at the same conclusion as you, it feels like a dumb false choice haha
- hn_throwaway_99 5mo agoI feel like you're missing the forest for the trees. Outside of any digital color space, aqua is still defined as "blue green" in plain English - I just used the CSS RGB definition as an example where it's literally defined as just equal parts blue and green.
- nodompa 5mo agoYeah but so is cyan, which is arguably more accurate of a name for the 100% blue/green combo that you're talking about. What I'm saying is why are you using an arbitrary specification to make decisions based on individual perception? I could say 0,255,255 is aqua but that doesn't really mean anything beyond digital color space, so why even use that as a metric for how green or blue something is beyond a perfectly color-accurate digital display using RGB as a colorspace? "Blue green" in plain English is not solely the 0,255,255 "blue green" that is in RGB space, it's like you narrowed it down to just that and ignored everything else
- jumploops 5mo agoCurious how this looks for red/green colorblind folks? Do they see everything beyond the initial green as a shade of blue? --Edit-- My red/green colorblind father just got back me with this result: > Your boundary is at hue 175, bluer than 68% of the population. For you, turquoise is green.
- parpfish 5mo agoI've got a color question that I need some opinions on: When I look at the green/blue boundary region on an HSV color wheel like the ones in this S/O thread [0], it appears as a white un-saturated region. If I look at similar layouts in other colorspaces (e.g., something perceptually uniform like Lab) I don't generally see this white patch. My question is: - I'm colorblind. Do other people also see a white patch there? - If this is a genuine problem with HSV, is there an explanation for why there's a hue angle that is unsaruated regardless of S value?

- ok_computer 5mo agoDon’t use hsv color wheel to intuit color space. CIE x,y $year_standard is superior to view color space and understand the tricolor values Z = f(X,Y) in every way. https://en.wikipedia.org/wiki/CIE_1931_color_space https://en.wikipedia.org/wiki/CIE_1931_color_space I think the bands you’re referring to are an artifact.

- OwlGoesHoot 5mo agoMan doesn’t understand teal the website
- Xcelerate 5mo agoMy mind was blown once when I heard multiple people calling yellow Gatorade (lemon lime) green. I have no clue how anyone perceives it that way.
- sudobash1 5mo agoAs other commenters here have noted, I found this interesting but a little frustrating. The second color it asks about is clearly cyan (or turquoise). For me, this is like showing an orange screen and asking if it is red or yellow. I understand that across cultures "orange" does not exist as a distinctly named color (it only got its name in most European languages around the 1500s), but as someone who was trained since preschool that orange is a distinct color, it would feel wrong to "round" it to red or yellow. I haven't had green-cyan-blue drilled into me the same way as red-orange-yellow. So sometimes I do "round" it. I might note how "green" some cyan river water is, or call something cyan "blue" when it is next to something kelly green. But when I just have a screenfull of pure cyan light, I don't know what else to call it. As a side note, I do wonder how differently a child would perceive color if they were taught more than 7 colors in preschool.
- irishcoffee 5mo agoTaught by whom? I hear parents are wonderful teachers. Also, lots of kids don't even go to preschool.
- MichaelDickens 5mo agoLogically I understand that cyan is directly between green and blue, but my brain believes it's 100% blue.
- red75prime 5mo agoBTW, cyan is very poorly represented by sRGB color space. I was delighted to see the real vibrant cyan of the Mediterranean sea.
- D-Machine 5mo agoAsinine and meaningless. Forces a classification on something that obviously anyone with fully-functioning colour vision will classify as "aquamarine" or "turquoise" or etc. This has nothing at all to do with colour perception, or, if actual differences in perception are involved, this test fails to distinguish those from individual differences in assignment to linguistic categories. EDIT: To actually test something like this, you need to make an assumption that cannot easily be tested or supported by evidence. E.g. say we could all agree that, generally, blue + orange is a more pleasant pairing than blue + green. One might then imagine a series of images using orange + varying interpolations between blue and green, with the prompt being "is this combination of colours more or less aesthetically pleasing than the last". The average cutpoint could then be interpreted as a subjective judgement of where e.g. teals become "more blue", from an aesthetic / complementary standpoint. But this test does nothing of the sort.
- 0xWTF 5mo agoI came back as with a measure of 174 and a label of "true neutral". However, I know enough about perception to know that this called for some hacking. So as soon as I saw the second color I realized I needed to look at something else. So each time after choosing and seeing the next color I looked around quite a bit, inside and through the windows at the outside (I happen to be in a Hawaii, so blues and greens are abundant) before choosing and I noticed significantly different color perception after looking around, specifically, I had more confidence in whether it was blue or green. I can imagine if you just stare at the colors and try to power through, you might get kinda irritated.
- al_borland 5mo agoI also got 174. I turned the brightness up on my phone (to about 65-70%) before starting, but that was it. No resetting my eyes between colors. Considering I’m red/green colorblind, and certain hues of green I see as gray, I’m pretty shocked by the result. I suspect having a binary choice helped a lot, as once it was no longer something I could consider blue, I’d call it green.
- ozten 5mo agoShowing the completion screen and giving the ability to use a slider to pick the center might be more useful.
- Insanity 5mo agoWould be cool to see a gender distribution. Women perceive more colours than men, wonder how it impacts this.
- SamInTheShell 5mo agoShowed me teal but only have options for blue and green. Teal ain't either.
- adxl 5mo agoI used to own a house in California which I swore was peach, my coworker told me face it the house is pink.
- Night_Thastus 5mo agoThis is also going to be very difficult because: * HDR vs SDR mode * Different monitors have different color replication ranges * Monitor and OS color and brightness controls (brightness affects color perception) * Interior lighting * Monitor technology (LCD, OLED, etc) Meaning even if a color was meant to be X, it just won't appear that way given the combinations above.
- still_grokking 5mo agoThis "test" makes no sense. Cyan, and especially turquoise are neither blue nor green, they are a mix (similar to orange between red / yellow). I had actually a very hard time to answer the questions, needed to overlay most of the color with some mostly white / light gray window and only squint at the color around it to decide. In the end my result was 176, which is almost the exact turning point for most people (and that even while my monitor is set to be more cold than default; but like said I had whatever my monitor shows as "white" to compare; even that "white" is likely technically slightly blue-ish). Color perception is anyway much more influenced by contrasts then anything else. (Likely similar to acoustic tones, which are very hard to name / locate absolutely than when comparing to some reference tone.) Besides the things mentioned in the about popup, blue is AFAIK the color we have the most receptors for. So it's imho quite "natural" that most people perceive cyan—which is technically the exact middle—as blue-ish, and of course the color left to it, turquoise, is green-ish (and as it seems, for most people, the mentioned turning point).

- kazinator 5mo agoThe test's gradient does not have even luminence/saturation. It needs to interpolate between blue and green in the CIELAB color space.
- cjbgkagh 5mo agoThis is like one of those eye tests where they switch between lenses narrowing in on the prescription. The question is really what shades of turquoise is more blue than green. I got 80 which is close enough, I think it’s really only the extremes that are meaningful. I tried simply alternating green-blue etc and got 60. I think adding some randomness and taking more samples (more questions) would help - I was worried that the prior color left a residual effect as a relative comparison was easier than absolute comparison. The extra random samples could help give an idea of confidence in that middle zone.

- mncharity 5mo agoThe xkcd color survey[1] was 16 years ago now. With the data available, there were various follow-ups. Many, including xkcd's own "take it for fun here" link there in [1], are now 404. But the strata[2] and word cloud[3] are still up, and relevant here. The data remains available. It was a TidyTuesday ("social data project") for 2025-07-08.[4] This response[5] looked at TFA. (This week's TT is ag tariffs.[9]) I just did a quick and sloppy search, so there's likely more out there. Curiously, I found AIMode and Bing/chat less immediately helpful than I'd have guessed. Years ago I used the xkcd data for a prototype web interactive for kids, which shader filtered video to selected colors... but it was overlapping rather than a partition, and I'd never leave out cyan.

- skygazer 5mo agoI'm not sure what's going on, but in Chrome my median point is heavily on the blue side but in Safari it's on the Green side. Also, at least in Safari, reset leads to a series of perceptually unchanging turquois screens -- it seems a bug. Refreshing fixes it for the next run.

- chirayuk 5mo ago"Your boundary is at hue 181, bluer than 87% of the population. For you, turquoise is green." Took it 3 times (90%, 85%, 87%). At least, I now know why sometimes I'm surprised that people call green things blue :) To be honest, there should have been a "neither" category, because that was frustrating to classify a color that is clearly neither. But I understand the need for a binary choice for this experiment. Turquoise `#40E0D0 ` feels green to me, while Dark Turquoise `#00CED1` , I can agree to consider as blue.

- altairprime 5mo agoMy numbers kept varying wildly from 174 to 189, in the same patterns across multiple devices (initial number different from stable next-five results), so I tried a few things. First I shifted the app to use P3 `oklch(.7066 .1611 $hue)` with range (150..210) centered on cyan at 180°, same as sRGB. No change, so it's not some sort of artifact of colorspaces. Then I upped it to 16 steps instead of 8. The window narrowed slightly, but the same first-then-the-rest shift kept happening. Finally I raised the random color static mask duration from 200ms to 5000ms. Scored 180 +/- 1. Huh. Makes sense, given the image persistence stuff I deal with. So, for those seeing that same variability I'd recommend editing that first (local response override index-blah.js, search `, 200` replace `, 5000` by hand, reload page) to get a more stable result.

- pibaker 5mo agoIt is mentioned on the about page but I still feel like pointing out that your response to this test has as much to do with your perception of colors as how green or blue your screen is and what kind of ambient lighting there is.

- naishoya 5mo agoYounger locals who have mostly or only known the LED think it's a bit odd, but just call them blue because that's the common convention and many youths may think that the former lights might have actually been blue. IIRC from when I moved to Japan the first time (30+ y ago) when the old lights were standard, being a wildly curious Gaijin enough to ask "why" about these kinds of strange contradictions, and having lots of exposure in that time to senior citizens who had the spare time and inclination to humor my incessant questions, several of these octogenarian to centarians remembered the introduction of the first gen traffic lights, when the automobile became common enough to require them; and this seeming contradiction was new; this was the explanation I have heard common across several distinct conversations in different towns: 1. 緑 "midori" as a character and word for green was not very common usage before the end of WWII. 2. The (pre-LED) lamps for all three were yellow bulbs viewed through glass filters that were 'red', 'clear-somewhat yellow', and 'blue' - so even though it may appear green, the blue was for the color of the glass. Also because 青い "aoi" has persisted in use for certain shades of 'green' - for example green apples and leafy fresh veggies; so this 'blue' seems to match the actual color of the light and has an implicit meaning for Japanese - in the sense of 'go while light is still fresh' - and Japanese humor is primarily Punny instead of being actually Funny, so this double meaning resonates even after switching to truly green LED light sources.

- sleepycat801 5mo agoTwo different screens (OLED vs LCD), two different results.
- moritzwarhier 5mo agoMy blue is in fact what others see as red, and vice versa, but I wasn't able to verify it yet!
- metalman 5mo agopeople are getting more stupid debate without evidence and logic is rampant the title is the clasic example of word salad, pretending to be valid conjecture , but only exists to cause distraction through "subjectification" or foucault off, already
- yapyap 5mo agoIt said that for me Turqouise is blue.. it is not, there was just no option for tuqouise
- zkmon 5mo agoThough everyone calls a solid blue color as blue, the actual visual perception or experience of that color could be entirely different. They just grew up calling that experience of their own, as blue color.
- mazurnification 5mo agoWhat a fun site. Obviously results will depend on the monitor. At the last screen picture which show "where is my blue" and the gradient from green to blue I moved it from one monitor to other - what a difference! Time to dig into monitors setting to get more consistency (or for new monitors - do the color change with time? - one is more lit in the morning by sun but other do not get direct sunlight almost at all- both are the same type). What is funny it did not bother me at all - I do not work with any graphics and color. But probably now it will :).
- mcalus3 5mo agoIn Polish language we commonly call turquoise "lightblue", so instinctively we'll have the boundary not at the middle of the turquoise, but between the turquiose and green, (i got hue 165, 95% of the population). We also call it "sea-color", but sea is also more culturally associated with blue than green.
- seszett 5mo agoIn French, turquoise is "bleu turquoise", so obviously blue. So I'm not surprised it says "For you, turquoise is blue." In Dutch it's called "appelblauwzeegroen" (apple-blue sea-green, yes it's weird) so it's not surprising either that my wife sees it as green I guess.
- junon 5mo ago> Your boundary is at hue 164, greener than 94% of the population. For you, turquoise is blue. No, turquoise is turquoise!!1
- phyzix5761 5mo agoWe never get to find out what the author's blue is
- pcblues 5mo agoI had a colour-blindness test when I worked at an abattoir. My job was to find odd things on a one third section of a side of beef as it went past and cut it off. 1500 or so per day. The test showed numbers created with blobs of close colours. The last test didn't have a number in it. Cheeky buggers.
- My_Name 5mo agoTried this on 2 monitors, made a difference of 77%-85% I noticed that what I was actually seeing later on was 'is this more blue or green than the last colour' due to my eyes adjusting to the previous screen and just seeing the difference.

- a3w 5mo agoTo all you nitpickers: I looked at a "white" wall and out of the window, and teal was slightly blue or green tinted afterward. Do that, too. Also, screen brightness shifted my result, as color calibration is of course an issue.

- isakmarr 5mo agoI'm colorblind :(
- neom 5mo agoI'm 60% towards green, and my turquoise is green, but I don't actually understand what the 60% means for me...60% of people agree with me the greens are green?

- NoSalt 5mo agoI know this may sound "petty", and it is definitely my ADHD coming out, but I hate online tests like this when they do not show you how many questions you have left vs. how many questions there are (i.e., 1/25 ... 2/25 ... n/25). It makes me way to anxious.
- robeLTDP 5mo agoExtraordinary experiment, very well implemented. I am sending the link to some daltonic friends to check what they see. Have you considered to allow the user to select between "color1" and "color2" to check where the boundaries among them are?
- godshatter 5mo agoI get a blank white screen in firefox on windows. I don't consider this to be blue, so I guess their blue is not my blue.
- nekiwo 5mo agoblank black screen on firefox android
- ulimn 5mo agoI guess it's not a browser issue. I tried firefox, safari and brave on macos and neither worked, even in private window. Bummer.
- teach 5mo agoYeah this worked for me last night, but I too get a blank screen today. In the developer console I see a CORS error for an attempt to load an SVG component from a CDN; I wonder if the dev pushed out a bad update
- rav 5mo agoLooking in dev console reveals that the issue is an error response from https://cdn.skypack.dev/canvas-confetti https://cdn.skypack.dev/canvas-confetti - at the moment that URL returns: A server error has occurred FUNCTION_INVOCATION_FAILED sfo1::qcpj5-1777386477345-b792e22509f4

- Multipassionate 5mo agoDamn, I didn't think about that :D Is color perception subjective? How do you measure that? Now it's driving me crazy
- efilife 5mo agoIt is, more than you think https://en.wikipedia.org/wiki/The_dress https://en.wikipedia.org/wiki/The_dress
- Multipassionate 5mo agoThanks! I also read a bit about this yesterday
- azepoi 5mo agoThis is largely cultural and language sensitive. I took the test as a french native speaker and got a green-blue boundary greener than the average population with the commentary "For you, turquoise is blue". Indeed it is. It is called bleu turquoise in french.
- b__d 5mo agoDon't forget to turn True Tone off on macOS/iOS before testing this.
