Is My Blue Your Blue?

• ivanjermakov 2y ago
  I think it's quite close-minded to call cyan green or blue.
• wazoox 2y ago
  "For you turquoise is blue". Sure, it's even called in French "bleu turquoise", never "vert turquoise".
• chiefrubberduck 2y ago

  Will vary a lot based on just window position and size... I got a very different score from the window fullscreen/centered vs off to the lower right when I first did it. My work monitor is not great, to say the least... will try on my personal display later. Towards the middle, I don't really see it as blue or green, but kind of accept that it's towards the middle. Half randomly selecting really.
• sublimefire 2y ago
  lol since I was a kid I called this color “electric”.
• pk-protect-ai 2y ago
  lmao: "Your boundary is at hue 168, greener than 85% of the population. For you, turquoise is blue." When there is no choice to select proper color and you only forced to tell if it is green or blue, despite that you see how many green is in that blue. When you forced to call cyan a blue ... Amazing declaration of BS.

• strogonoff 2y ago
  If I call “blue” the same wavelength you call “blue”, it does not mean your blue is the same as my blue.
• aucisson_masque 2y ago
  > Your boundary is at hue 168, greener than 85% of the population. For you, turquoise is blue. I mean turquoise isn't blue and isn't green, what difference it makes if some say it's closer to green and some other say it's closer to blue. It's just turquoise.
• nocman 2y ago
  "For you turquoise is blue" - no, for me turquoise is turquoise, but you did give me that as an option. Multiple times I thought to myself "I would not call this color blue or green, it is some variety of blue-green". So in my opinion that makes this whole test kind of nonsensical.
• eahm 2y ago
  Did it yesterday right after I saw the link once and got 185 (bluer than 97%..) but I've always had some passion for colors and variations, that's also why I like CSS. Anyway, funny to share but nothing changed in my life after that.

• itslennysfault 2y ago
  Is there a reason this code is so complex? For example, the code where it picks the next color uses this sigmoid function ( https://github.com/patrickmineault/ismyblue/blob/main/src/utils/glmUtils.js https://github.com/patrickmineault/ismyblue/blob/main/src/ut... ) to increment the hue. Is there a specific reason you didn't just have a list of a dozen or so colors and shuffle the array when the app starts? Just curious about the reasoning behind this and the value it provides.

  • lolinder 2y ago
    To be relevant to blue/green wouldn't they need to not just collect a boolean but collect the type of colorblindness?
    • AlotOfReading 2y ago
      It gets complicated if the goal is perfect accuracy. Cone sensitivity also varies on an individual basis even for color-normal people. Worse, the transfer function of the eyeball also varies with age as your lens yellows and internal fluid clouds a bit. Even holding those constant, brains do a lot of processing that maps what your eyes can physically capture into perceived colors, which are significantly influenced by upbringing. Plus, screens and ambient lighting. It's a lot of variables.
  • jameshart 2y ago

  • pminimax 2y ago
    Author here, it started out with: ``` Can you help me make a website called is my blue your blue? I want to make a website that is in vue.js that allows one to determine the boundary between their perception of blue vs. green. It should use a golden ratio search to find the midpoint between blue and green. It should have the color be the color of the background, and it should have two buttons, blue and green. If they pick green, you should show something bluer, and vice versa. ``` It offered a starter with vue and tailwind, then I asked to add a supabase backend. I took maybe 5 hours to get the original version, which I tweaked until I got about 800 initial responses so I could show a population curve. Later I modded it with cursor to add an about section, fit a proper GLM rather than a simple golden ratio estimation method, and the d3 animation at the end.
• avodonosov 2y ago
  Great site. I wish they had a Turquoise option.
  • TechRemarker 2y ago
    I assume that would defeat the purpose, since turquoise is blue and green. And while for most the more initial more obvious blue or greens are easier, when close to the middle of in between blue and green (aka turquoise), that's where it can get confusing, and this test helps to show if your perception leans more towards blue or green and by how much.
    • avodonosov 2y ago
      Then maybe allow non binary choice. Like 0.7 green / 0.3 blue. Becase when I see a mix of blue and green and there is only two buttons, I choose green. Or maybe I should treat the buttons as "> 0.5 green" and "> 0.5 blue". Imho violet vs purple are difficult to distinguis (classify), maybe they can add a page for that too. These two colors are not spectral neighbors, so may be more interesting. One more note - modern RGB displays do not produce real turquoise, just combinations of G and B. Are RGB(0,1,10) and RGB(0,10,100) on the same position of the scale between green and blue? On the final diagram, how is the horisontal axis computed?
      • TechRemarker 2y ago
        > Becase when I see a mix of blue and green and there is only two buttons, I choose green. If you choose green, because you see a slight more tint of green than blue, yes, that's what you should do for this particular test. Just as you should choose blue if you see slightly more blue. For many when close to the middle hard to tell since have to go with your eyes and gut. But if anytime you are unsure if blue or green, if you always choose green regardless, then the test presumably wouldn't provide accurate results. > Or maybe I should treat the buttons as "> 0.5 green" and "> 0.5 blue". Yes, with each color they show, it's asking you if you see green (aka more green than blue) or blue (aka more blue than green). With the test starting off easier and then shades much closer to the middle (either left or right of the middle) where much harder to tell without a color picker, and everyone's eyes will be different and close to the middle you will probably see most as either blue or green.
• hydrox24 2y ago
  Neat website, and lovely to use. I wonder if the test needs to be slightly more sophisticated? My results seem to depend on whether the starting colour is blue or green. If it starts with blue I will categorise more of the turquoise as blue, and if it starts as green I will categorise more of it as green.
• Jeremy1026 2y ago
  Interesting. My wife and I both took this. We used the same laptop at the same screen settings. I'm slightly more bluer than she is, but we are both pretty squarely less green.
• ww520 2y ago
  Does it depend on the monitor's color setting?
  • epiccoleman 2y ago
    I mean, it obviously does, to some extent. I can certainly manipulate my settings to make colors very different than the "default."
• fogleman 2y ago
  I think this is flawed. You quickly end up on a color that's clearly not "blue" or "green" and you're unlikely to keep hitting "this is green" several times in a row, conceding that ok, fine, maybe this is blue, whatever. You're basically measuring how many times people are willing to click the same button in a row. Edit: Possible improvements: changing the wording to "this is MORE green" and "this is MORE blue" and randomizing the order in which they are shown, somehow. I realize you're just doing some kind of binary search, narrowing the color range. This is not to mention color calibration of your monitor, or your eyes adjusting / fatiguing to the bold color over time...
  • jsharpe 2y ago
    Exactly my thoughts! Thanks for putting it so clearly.
  • fsckboy 2y ago
    >I think this is flawed. You quickly end up on a color that's clearly not "blue" or "green" and you're unlikely to keep hitting "this is green" several times in a row, conceding that ok, fine, maybe this is blue, whatever. I agree with you, the whole thing is flawed when it could be better. When you ask the question "is my blue your blue?", you are evoking the old philosophical question, and it's a question about color perception, not words. This test did not test color perception, it tested "what word do you use?" I think of blue as a pure color, and green as a wide range of colors all the way to yellow, to me another pure color. so if there's any green at all in it, I'm going to call it green. (maybe it's left over from kindergarten blending "primary colors". also, while I like green grass, I don't like green as a color, so any green I see is a likely to make me think, ew, green) But in terms of what I see, I can only assume I'm seeing the same thing as everybody else is because the test is not testing it. Just because I call something green doesn't mean I don't see all the blue in it. >Edit: Possible improvements: changing the wording to "this is MORE green" and "this is MORE blue" and randomizing the order in which they are shown, somehow. I realize you're just doing some kind of binary search, narrowing the color range. yes, the test should show you pure blue, then a turquoise mix, then pure green, and a ... etc. It should also retest you on things you already answered to measure where you are consistent.
• joegibbs 2y ago
  I got "Your boundary is at hue 167, greener than 86% of the population. For you, turquoise is blue". I think I consider darker and yellower colours as green - for instance tennis balls are firmly green to me, but a lot of people say they're yellow. I wonder if this has anything to do with your upbringing. I grew up on a farm in a dry part of Australia, where the grass didn't often get very green. Most of the year it was yellow. If you associate green with grass and the grass is yellow, maybe you associate green with a yellower colour?
  • epiccoleman 2y ago
    I got a very high "green" threshold too - 95% averaged across three runs, since my first result seemed surprisingly high. It's funny though - I feel like I'm less likely to go green on the other direction too. I'd probably say a tennis ball is right on the line, and seems more yellow than green to me too. Maybe I'm some sort of green gatekeeper, and I don't want to dilute my personal definition with lesser greens. Green is my favorite color, I'd say, so maybe that's something to do with it.
  • Jeremy1026 2y ago
    It's very cultural. For example, Japan used the same word for green and blue, so their green light on traffic lights is as blue as possible while conforming to international standards for the light to be "green". Also, there is a pretty well done video by Vox on how color names are influenced by culture https://www.youtube.com/watch?v=gMqZR3pqMjg https://www.youtube.com/watch?v=gMqZR3pqMjg
    • WesolyKubeczek 2y ago
      Thank gods at least red is red. In all rulebooks, lights are red-yellow-green, but in many places, I can see red-amber-turquoise. Now a sure way to get a traffic police officer livid is to call the yellow light “amber” or “orange”…
      • pests 2y ago
        My friend got a "Running an Amber" ticket when we were teens outside metro Detroit, MI. I had never heard it called that color before but that small memory is always on my mind when the light changes as I'm crossing.
• hettygreen 2y ago
  Am I missing something? The ambiguous ones are neither blue nor green, they're just cyan.
  • TechRemarker 2y ago
    Yes, that's the point of the test, to see how you perceive the ambiguous ones. That is, at the end it shows the chart with the left 50% is green and right 50% is blue. The turquoise in the middle is what is hard to tell if green (aka on the left 50% or blue aka on the right 50%). For many the result line isn't down the middle but more to the left or right, and thus shows if you see turquoise (the ambiguous colors) more as blue or green. The text at the bottom of the test should put the answer in words/numbers.
    • the__alchemist 2y ago
      It sounds like he or she perceived the color in question as cyan, which isn't an option.
      • TechRemarker 2y ago
        Since cyan means 50% green and 50% blue, other than exactly in the middle of the chart, all the colors shown are either to the left of cyan(the middle), or to the right. So all the colors are either slightly to a lot blue or slightly to a lot green. This test is testing where everyone middle essentially is. If there were as cyan/turqouise option, that would be a very different test, I imagine essentially testing to lines, where the line between blue and cyan/ambiguity begins and the line between green and cyan/ambiguity begins requiring I imagine several more questions to get that answer and would only then be showing two lines on the graph, vs this test which is able to say if you lean more to the right or left of the middle of blue to green.
  • kstrauser 2y ago
    If you had to say that cyan was more blue or green, which would you pick?
• mbb70 2y ago
  Hey I got 179, which the site says is 1 away from exactly halfway. Being good at the difference between green and blue is normal to want and possible to achieve!
• doe_eyes 2y ago
  I suspect it tests your monitor and monitor calibration as much as your color perception. In particular, sRGB displays have a pretty severely limited green gamut. If you have a wide-gamut display, the test is probably gonna appear different. But another problem is with displaying the colors essentially full-window, which is going to be nearly-full-screen for many users. When we're staring at a screen with a particular tint, our eyes quickly do "auto white balance" that skews the results. It's the mechanism behind a bunch of optical illusions. To address that last problem, I think the color display area should be much smaller, or you should be shown all hues at once and asked to position a cut-off point.
  • chimeracoder 2y ago
    > To address that last problem, I think the color display area should be much smaller, or you should be shown all hues at once and asked to position a cut-off point. If you're doing this on a phone, try holding your phone at arm's length and against a white background (such as the wall or ceiling) and doing the test that way. Assuming you have redshift/night mode disabled, I suspect you'll end up closer to the median.
  • myworkinisgood 2y ago
    I was initially running the test with redshift enabled and was getting 95% towards blue. After reading this comment, went and disabled the redshift and got a consistent 50% median.
  • sandworm101 2y ago
    These sorts of tests also need to be done in controlled background lighting. Whether people are doing this in a dark room, in a sunny kitchen, or under green led lighting would be a greater factor than anything being tested.
    • AlotOfReading 2y ago
      I don't think that's necessary for an informal test. Human color perception is extremely good at compensating for that and modern screens are relatively uniform and uniform besides. Cultural differences like the person downthread saying they consider anything with the slightest hint of green to be "green" seem far more impactful.
• whalesalad 2y ago
  Your boundary is at hue 187, bluer than 98% of the population. For you, turquoise is green.
• cynicalpeace 2y ago
  You and I have the same name for things that are blue (mostly). That's what this test examines. But what if what I see as blue is actually your red? Is this even knowable? Like if you were to see through my eyes and you looked at the sky would it be what you called red?

  • silisili 2y ago
    I think most people have this realization and question, probably as children. It's probably impossible to know for sure. But I largely think we see them similarly, mainly because of favorite colors. Few people like orange, brown, tan, pea green, etc. If we all saw colors differently, I feel like there'd be greater variety in favorites.

Sixty percents of the time I was thinking "in between".

  You might ask, "What makes an artist an artist?" It's the seeing. Artists see differently (and there are some skills too of course). Meditation, drugs and some other stuff change the way you see too. So perception is definitely a variable and not a constant. So ya, the seeing of blue varies.

It is a neat site, but I guess I don't understand the point of this is. Another version with vehicles could say "To you a Van is a Truck", and you would get some results on how many people classify a Van as a Car or a Truck... but the question is flawed to begin with, and thus so are the "results".

  I stopped at the first one I could not call blue or green. If I were to call it blue or green, it would not only not be reflecting what I think, but I could not guarantee that if I'm show the exact same color again, that I will go the same way. So I felt there was no point in continuing. This is a problem in the method; there needs to be a third choice, so that the user can always answer (at least if the test color is always in the blue-green gamut). It could work with two choices if the user were instructed to randomly choose in the event of indecision. I mean, truly randomly, like by means of a fair coin toss. But that could just be implemented for them by a third button. That button could then just record their indecision rather than randomly choose between blue and green, so you have better data. Without a third choice, or properly randomized behavior, you have bias problems. For instance, a certain user who likes the blue color might always say blue when not able to decide. Another one might always go for green. Yet, those two users might exactly coincide in what they unmistakably call blue, green and what triggers hesitation/indecision. (I realize that no matter how many bins we have, there are boundary indecisions, like not being able to decide between green and blue-green. What range constitutes indecision is also subjective.)
  • phito 2y ago
    Totally agree, I stopped at the second one because it was neither green nor blue
  • rotidder 2y ago
    That exactly is the point of the test though. Not to test whether most people call 100% blue blue, or 100% green green. It is to test at which point of the "inbetween" colors people switch from blue to green or vice versa. It forces you to decide whether the color you see is "more blue" or "more green", since after all they're all just a mix of blue and green.
    • Timwi 2y ago
      Well for me, personally, blue and green are simply not adjacent, so there's no point where green turns to blue without going through an intermediate color. This might well be due to my extreme exposure to computer colors, where the in-between color is usually called cyan, or sometimes teal or aqua. When I see cyan, I cannot sincerely say that it looks “more blue” or “more green” to me, any more than an orange tastes “more apple” or “more banana”.

• marcus_holmes 2y ago
  I'm red/green colourblind, so this was interesting to compare my green against my blue. The thing I find being colourblind is that I value colour less than shade. Colour signals, even when I can tell them apart, are just less important to me than to non-colourblind people. I most recently noticed this playing Valheim with my wife. There are red mushrooms in the game, surrounded by green foliage. I noticed that I have trouble spotting them, even though I have no problem seeing that they are red and the foliage is green. To her, the mushrooms stand out as being very visually different from the background and immediately noticeable. To me, they just aren't that distinct and get quite hard to spot. So while I got the green/blue distinction to within 80% of the population, despite my shitty colour perception, it just didn't matter. At some point in the process I got to "I really don't care. I would ignore the signal that any further difference in colour is sending". As you can guess, I have fascinating talks with designers and artists, to whom the differences really matter. I understand that colour is really important to them. I just don't see it.
  • lll-o-lll 2y ago
    I have normal color vision, and color just doesn’t matter to me (I can never remember the colors of things, and distinction by color doesn’t help me much). I’m not discounting your theory, but I think there must be a little more to it.
    • AlotOfReading 2y ago
      Not the person you're responding to, but also colorblind and I strongly relate to what they're expressing. It's different than not being able to remember colors. I can see (most) differences, but I need to actively focus on seeing to do it. For example, one CI system uses red/green stoplight emojis for test status. A given run might have 50-100 of them. Trying to see which ones are red means actively looking at each individual status and thinking "what color is that?" because my brain simply doesn't register reds as "jumping out" in the sea of green.
      • marcus_holmes 2y ago

• mattdesl 2y ago
  Surely this should be using a perceptually uniform color space like OKLab rather than HSL!
  • lifthrasiir 2y ago
    While that would change the distribution of threshold hues (partly due to the non-linear mix of blue and green, as sRGB transfer function wasn't inverted), it shouldn't change the conclusion itself. Also it would be hard to constantly change the lightness in such systems, as the #0000ff green would have a much larger lightness than the #00ff00 blue and there are some gaps outside of the common sRGB or even P3 color space.
    • mattdesl 2y ago
      Pure RGB primaries gives an easy target for “red” and “green” endpoints but that’s about it. Ideally the test should consider two endpoints with uniform lightness and chroma, and just shift the hue to form in-betweens. The transition from blue to green in RGB (or HSL) is not linear in these attributes.
      • lifthrasiir 2y ago
        That is what I believe the original comment meant to say: convert to some color space where linear interpolation for non-hue axes would be meaningful. In my knowledge, such linear interpolation will require the tone mapping due to out-of-gamut colors, and the tone mapping itself is fairly subjective.
        • mattdesl 2y ago
          Not quite—you can choose a ramp that will remain in-gamut for sRGB, eg try shifting hue here: https://oklch.com/#72.67,0.121,240.19,100 https://oklch.com/#72.67,0.121,240.19,100 Even if you were to use a more saturated ramp, I suspect that discontinuities due to gamut mapping with a good algorithm[1] should be less than the discontinuities due to lightness and chroma shifts in HSL, but I could be wrong.

• grishka 2y ago

  For me, the results weren't even stable, but varied from run to run according to what colors were shown. And the first time, it randomly showed me a bunch of blues and I thought it was broken. It told me my perception was bluer than 99% of the population. But all the subsequent runs were very different, and not stable.

  I had this result: > Your boundary is at hue 171, greener than 72% of the population. For you, turquoise is blue. Of course there is a monitor and eyes component/biais tonthe measurement, but I also think this reveals something cultural. In France we call this color "bleu turquoise" so "turquoise" is not a color per se but a qualifier for the color blue. Interestingly, at some point in the test I really had a hard time choosing between green and blue and precisely thought "it's a perfect turquoise so just between the two, how to choose?" so I closed my eyes and looked at it again and decided… green for this one! I wouldn't have expected the final result it gave me!
  • p4bl0 2y ago
    I just found this in the "about" section of the website: > In early experiments, we found that people's responses cluster around 175, which coincidentally is the same as the named HTML color turquoise. This is interesting, because the nominal boundary between blue and green is at 180, the named HTML color cyan. That means most people's boundaries are shifted toward saying that cyan is blue. That last sentence surprises me. At least in French, cyan is also considered a shade of blue. For turquoise I can understand that people would call turquoise green, but isn't cyan blue for everyone?

• smcameron 2y ago
  I expected this to be about qualia. It's not. What I percieve to be red might be what you perceive to be blue, but we have no way to know this, because we will both call it by the same name. We have almost no insight into the qualia of others. Colorblindness is a chink in this armor. Not that I consider this a novel insight, it's something I thought of while a 10th grader back in 1984, and subsequently read about in books predating my own thoughts, such as Douglas Hofstadter's Metamagical Themas or Godel, Escher, Bach, or some other book I can't recall, though it seems quite obvious in any case.

  At 0% brightness, my hue is 167, bluer than 85% of the population. And at 100% brightness, my hue is 176, bluer than 69% of the population. This means that turquoise is green in sunlight and blue otherwise.

  By chance, I was reading earlier today about the dilemma of recreating 'Tyrian purple', aka 'Royal purple', since knowledge of making (something like) it from sea snails was lost long ago (long before it was 'created in the lab' by Perkin in 1850s, igniting the German aniline industry). And the old faded art works (back when it was high fashion) are not so reliable either. The Wiki sez [0] that in 1998 the process was thought to have been discovered (who can be sure?) "True Tyrian purple, like most high-chroma pigments, cannot be accurately rendered on a standard RGB computer monitor" and shows 2 quite different swatches.

  You have a meta header that sets a strong blue theme-color on the top of the browser. I feel like this might be biasing the results on iOS Safari because, compared to this blue, turquoise appears comparatively green.

  So at the end, I'm shown a full-screen gradient from green to blue, with a line showing where my personal boundary between green and blue lies. Except that when I look at that gradient, it seems to me that the actual transition lies much further to the left, roughly in the middle of the screen: i.e., I'm being told that I consider a significant range of colours to be green that, on this final page, appear to me to be quite clearly blue.
• hooby 2y ago
  I'm actually of the opinion, that blue-green colors like teal or turquoise are both green and blue at the same time. Basically a mixture. Having to pick just exclusively one - blue OR green - for such colors just feels, wrong and arbitrary? You could also make a website that shows various shades of purple - and ask people is it blue or red? Well, both! Purple is a mixture of both blue and red. Why treat teal differently than purple?

• alex-moon 2y ago
  I'm doing it over and over again and getting different results each time, though the results seem to cluster around 174. I think part of the problem is that the response is primed by whatever you responded most recently, which means the final answer will tend toward (or away from?) whichever colour was shown first. (Might just be a me problem.)
• vullim 2y ago
  I clicked "This is blue" whenever a green came up and "This is green" whenever it showed me a blue. Interestingly it didn't bother with any turquoises or cyans when I did this, it only showed me unambiguous blues and greens. At the end it told me "Your boundary is at hue 180, bluer than 85% of the population. For you, turquoise is green." Which I would've thought was impossible to discern from my choices.
  • vullim 2y ago
    Furthermore, there's some randomness to this. If I click only "This is blue" the hue boundary is different each time, in the end result. The lowest I got was "hue 134, greener than 100% of the population". Same for clicking only "This is green", with the highest observed boundary as "hue 226, bluer than 100% of the population".

You should consider colorblind people aswell, this will make the results more interesting.

  Nice. But... this reminds me of an issue many years ago when i worked in a design agency. A client's marketing manager had been sent printed samples with spot colours for sign off. She was complaining about the colours not being correct... It turns out that someone in her team had taken photos of the printed items and emailed them to her because she was on the move. The correctly printed items were photographed in bad light with a camera phone, maybe it was an iPhone 3G around that time... which were then compressed and sent on email, and she was then comparing them on a poor quality PC laptop display... Sadly she wasn't the only one to raise a similar issue. Another guy was notorious for zooming in on 72dpi low quality images and complaining that the logo wasn't legible or sharp enough :D
• redrobein 2y ago
  Interesting. Does anyone else see a band of green in their blue? My boundary is at 170. Greener than 85% of the population. This point looks like the transition between blue and green to me, to the right I can see the gradient go to blue then to green again, then back to blue. So there's a green band in the middle of my screen.

  The websites shows a slope from green to blue across turquoise, but al most of this is almost certainly calibration error, and people being forced to say blue or green when they want to say turquoise. The true graph is most probably a very small slope on the green and blue ends, and rectangle of measurement error in the middle. The "you are 70% greener" conclusion is a textbook example of false precision that ruins the science.

  This is a classic problem of trying to choose a single label for anything. There are very few absolutes… maybe none. I like this test applied to an apple. . With no bites taken, is it an apple? (Of course) Now take a bite. Still an apple? (Most would say yes). Keep taking bites until it is just a core, or an even just a seed. Then? Maybe my favorite is just the boundary of one of us humans. Where is the boundary between me and not me? Obviously it’s on the outer edge of my skin. But zoom in a lot, and you have this blue/green binary fit problem.

  I've taken the test multiple times, and ended up with my boundary being both greener than >70% of the population and bluer than >70% of the population in separate attempts. And I know my color perception to be good at distinguishing hue - it's just that I don't have strong opinions about categorizing it in this space. I'm pretty sure there's some hysteresis going on - if we randomly end up in the ambiguous zone on the bluer side, we'll be pressing "blue" every time a small change happens, because it's basically the same color. Until the changes add up so much that we're out of the ambiguous zone on the green side - and now our "border" is far on the green side. But if we started on the other side, entering the ambiguous zone from the green side, it'd take a big cumulative change before we press "blue".

  I'm curious how the aggregate results from this test would compare to the exact same test named "Is my green your green?" I could see the title influencing some of the more nuanced decisions in the middle.
• nsew 2y ago
  If you guess the obvious wrong answer the choices between green and blue become more and more obvious. If you continue to guess wrong you end up with a boundary hue of 179 or 180 (bluer than 85% of the population). How is this possible? I'd suspect someone making the choices here would be colorblind and well into the 99.9th percentile.

  I know my blue isn't the same as it was before Cataract surgery. The world was a lot more yellow then. The benefit of not doing both eyes the same days in terms of complications and going blind is obvious. It gave me an A/B test as well to actually see the difference myself.
• whiterock 2y ago
  I sent this to two friends and we got 163, 164 and 165. We are all maniacs in the +90% percentile I suppose xD.

  The About pages notes that this was built with Claude Sonnet 3.5. Nice to see these real-world LLM uses where people who aren't front-end developers can share cool things.

  If you want to have fun, try printing a logo with nuances of green on your CYMK printer. Nuances on the screen become a flat blob.

  Author here. I added fields so you can specify your first language (relevant link: https://en.wikipedia.org/wiki/Blue%E2%80%93green_distinction_in_language https://en.wikipedia.org/wiki/Blue%E2%80%93green_distinction...) and colorblindness. FAQ: * I can't know your monitor's calibration, your ambient light, or your phone's brightness. Obviously, this will affect the results. However, I am tracking local time of day and device type, from which we should be able to infer whether night mode and default calibration has any aggregate effects. Anecdotally, thus far, I haven't found any effects of Android vs. iPhone (N=34,000). * The order is randomized. Where you start from can influence the outcome, but methodologically it's better to randomize so the aggregate results average over starting point. You can run the test several times to see how reliable this is for you. * It's common practice in psychophysics to use two alternatives rather than three (e.g. blue, green, something in the middle). It would be a fun extension, which you can handle with an ordered logistic regression. The code is open if you want to take a shot at it: https://github.com/patrickmineault/ismyblue https://github.com/patrickmineault/ismyblue * I will release aggregate results on my blog, https://neuroai.science https://neuroai.science * I am aware of most of the limitations of this test. I have run psychophysics experiments in a lab on calibrated CRTs during my PhD in visual neuroscience. *This is just entertainment*. I did this project to see if I could make a fun webapp in Vue.js using Claude Sonnet, and later cursor, given that I am not highly proficient in modern webdev. A secondary point was to engage people in vision science and get them to talk and think about perception and language. I think it worked!

    When done on my Xperia cell phone, even a small shift in screen orientation made the green leaners into obviously blue. Might be worthwhile capturing phone position if you can.
  • Normal_gaussian 2y ago
    This is a fantastic site. My partner and I were well aware of the limitations, but it has clearly demonstrated our difference in perceptions in a way we were both happy with. Being able to see where your partner lands relative to you is deeply satisfying.

  When you show the distribution at the end, it'd be cool to be able to select my own threshold not based on the test results but my reaction in the moment to the color palette. I found that the distribution did not line up with where I'd draw the line.
• splwjs 2y ago
  I remember being in school and thinking that "what if my (color) is your (other color)" was a cool question, and then later I think I reasoned out that color is measurable so the actual color is objective, and the differences between different people is just like... rods and cones that are somehow different between people aka partial colorblindness. So I don't know what this is.
• Matheus28 2y ago
  I did it twice and landed on exactly 168 each time. Can’t wait to show this to friends and argue.
  • remram 2y ago
    Twice on the same monitor?
    • Matheus28 2y ago
      Yes. I’d assume it’d be slightly different on different monitors

  "Your boundary is at hue 172, greener than 63% of the population. For you, turquoise is blue"
• QuercusMax 2y ago
  I think it would be better to show a bunch of colors randomly and let you pick your blueness / greenness from that, instead of slowly converging to an answer with extremely similar choices near the end.
• JoblessWonder 2y ago
  I used to have a lot of anxiety wondering if what my brain perceived as "Blue" was the same shade of "Blue" to other people. Like, sure, the sky is blue and a similar color to water for everyone.... but what if what I see as blue is actually red for other people and there is just no way to confirm because that is how our brain processes that frequency of light? I'm sure it isn't actually possible to confirm... but I was always interested in it. Late addition to comment: I just found this article that explains it well and has some theories on it: https://www.livescience.com/21275-color-red-blue-scientists.html https://www.livescience.com/21275-color-red-blue-scientists....
  • kolbe 2y ago
    Ultimately it doesn't matter. Your "blue" is just a translation of that frequency to some distinguishable impression to allow you to see. But it's a good bet that the same wiring that went into your brain making that translation also went into other brains.
• dianne05 2y ago
  Actually that is a test only , we agree both to testing my monitor only, and experiencing what is cyber space.. atleast soon I am ready it could be happen...

  I'm reminded of xkcd's color survey map[1] and fun visualizations[2]. And a similar paper[3] with an interactive[4]. Note the variation between linguistic groups, and high variance among individuals. Might be interesting to compare the results of TFA. There's also work on using google image search to learn color from names.[5] I was sketching a kids app for "use phone camera to name and collect colors".

• dariosalvi78 2y ago
  There's an issue of language here. For me, an Italian, blue is dark and "azzurro" is light. I played the game assuming that "azzurro"=Blue but I guess that sensitivity is skewed by semantics here. You can try to capture mother language too and see how it affects the statistics
• dehugger 2y ago
  169 here, for the guy scraping results.
• tigerlily 2y ago
  Hmm, night mode on iPhone definitely messes with me. Without it score average, but with night mode on I got 185. Quite amazing! I can see this tool being useful for correcting monitor settings when making pixel art for games :)
• devit 2y ago
  It needs three choices, since many of the colors are blue-green and the "this is blue" or "this is green" is essentially a random choice.
• seizethecheese 2y ago
  Interesting. I am red/green colorblind, so would expect that I would be less sensitive to green. It turns out, my blue is 98% bluer than others. Could it be that what determines this is how much your mind overcompensates for a lack/abundance of cones in the eyes?
