I love the “nothing in nature is true black so don’t use #000000” argument.
Correct, nothing is, and your #000000 won’t be either once it’s shown on a physical screen.
- mikae1 4y agoI find there's often a high degree of educated comments here on HN. But, when it comes to monitors, readability and the physics of light something happens. #000 on #fff won't burn out your retinas. :)
- hnbad 4y agoThere's a difference between using "soft black" and using low-contrast gray like you're Apple in the 2010s. The thing about pure black isn't that it's unnatural, but that when paired with white its contrast can actually be uncomfortable and less accessible than a slightly toned down color combination (especially on full brightness).
- mikae1 4y ago> The thing about pure black isn't that it's unnatural, but that when paired with white its contrast can actually be uncomfortable and less accessible than a slightly toned down color combination (especially on full brightness). Can you find a citation for that statement? WCAG 2.1[0] mentions minimum contrast, but not maximum. The success criterion page itself is written in #000 on #fff. :) https://www.w3.org/WAI/WCAG21/Understanding/contrast-minimum.html https://www.w3.org/WAI/WCAG21/Understanding/contrast-minimum...
- httpsterio 4y agohttps://dm-ed.com/info/contrast-sensitivity/ https://dm-ed.com/info/contrast-sensitivity/ A lot of high contrast combinations are less accessible and even if it doesn't make the text illegible, too much contrast is going to be a strain on the eyes for most people. Generally, WCAG AA or AAA is enough for most people and you hit that already with #555 on a white background. Something like #1a1a1a is close to the darkest I'd use in most cases.
- rectang 4y agoI'm sympathetic to the idea that some people need reduced contrast to read comfortably. They are in the same boat as people who need maximum contrast because of other visual impairments, most commonly focal issues. Why wouldn't people who need less contrast simply reduce the contrast on their monitors, though? It seems to me as though designing for those who need low contrast excludes those who need high contrast, but not the other way around. From your link: > The solution for contrast sensitivity > If you feel that your child may be suffering from this issue, the first thing to do is test some tinted acetate sheets placed over the page of text.
- alpaca128 4y ago> Why wouldn't people who need less contrast simply reduce the contrast on their monitors, though? Because I don't want to make everything else look worse just to lower contrast in text? And support for low contrast doesn't mean excluding others, it can just be a setting. Like Windows has been doing for a long time with its high-contrast mode. Websites and apps are increasingly adopting dark themes, next we should push for a switch between high and lower contrast. It's just as easy from a technical standpoint. Browsers are already pretty far, letting the user set specific fonts and font sizes, and Firefox' reader mode and its options are great as well.
- rectang 4y agoMy beef is with letting aesthetics trump accessibility. If a site provides a widget where contrast can be beefed up, probably part of the dark-mode / light-mode widget, that seems OK.
- mstolpm 4y agoI don't have a citation, but a personal anecdote: When I was in charge for a website, an elderly woman contacted us and asked, if we could change the black text to a dark grey. She mentioned that the contest was too high, resulting for her in seeing ghost images of the letters. I changed the text color from black to something like #eee or #ddd (at least a change barely noticeable) and she later contacted us to to thank us, so it must have had an effect on her. So it seems, for some people with limited eyesight, contrast can be too high as well. However, I agree with the generell sentiment that in modern web design, contrast is often too low.
- Koffiepoeder 4y agoI think you mean #111 or #222. The ghost letter thing is interesting to me. Was the background plain white or more of a broken white?
- intrasight 4y agoMy first job was building monitoring software used by operators of nuclear power plants. I have no citations, but they leveraged some specialized human factors research that said "don't use black". The standard in the industry is dark grey.
- AlanYx 4y agoI'm not the original poster, but here's an academic paper that found that 8:1 luminance contrast is optimal for reading, after which readability actually decreases: https://www.sciencedirect.com/science/article/abs/pii/S0169814199000402 https://www.sciencedirect.com/science/article/abs/pii/S01698... As far as I can tell based on what I've read, there can be a conflict between users with accessibility needs, where you may want as high contrast as possible, and typical users, where excess contrast may impair readability in some cases. The WCAG minimums are within the realm of reasonable for both sets of users though, so there isn't really an excuse not to meet those minimums.
- tveyben 4y agohttps://ethanschoonover.com/solarized/ https://ethanschoonover.com/solarized/ Has some interesting - scientific based - design choices regarding how to handle contrast…
- rectang 4y ago> The thing about pure black isn't that it's unnatural, but that when paired with white its contrast can actually be uncomfortable and less accessible than a slightly toned down color combination (especially on full brightness). For those with fuzzy vision (obviously an extremely common situation), contrast is reduced naturally when the black and white bleed into each other. Reducing contrast harms those users, belying your "actually less accessible" assertion.
- userbinator 4y agoespecially on full brightness Then turn down the brightness. Pure black/white should never be uncomfortable, if it is then your monitor needs adjusted. In fact I suspect a lot of this stupid low-contrast trend comes from designers who don't know that and are trying to compensate for it in software. Monitors come with the brightness set ridiculously high so they'll look good in a showroom (and possibly to make the backlight wear out faster, but that's another rant...), but it's definitely not where normal use should be, unless you're in direct sunlight.
- TAKEMYMONEY 4y ago> Then turn down the brightness On all my computers? And my phone? And my tablet? And my... You could say the same about sites where the body text is set unreadably small. "Just zoom in!" It does not persist across devices, sessions, users etc the way a well-designed site would.
- jeroenhd 4y agoI have my phone on auto brightness and my displays on max brightness. Black on white is perfectly readable to me, even in the dark. I don't know what ultra HDR monitor you're using or what light sensitivity issue you may have, but I don't want to have to install addons in my browser because you can't find the brightness slider.
- TAKEMYMONEY 4y agoLight sensitivity issue? > I don't want to have to install addons Sounds like you don't need to, you're happy changing the setting in many places (every device), than one (a stylesheet) > because you can't find the brightness slider "Make the user fix it" was the old thinking. Now we consider a more robust set of platforms, devices and users.
- userbinator 4y agoNow we consider a more robust set of platforms, devices and users. What a bunch of doublespeak BS for "now we want to keep the users stupid and unknowing."
- kuschku 4y ago> #000 on #fff won't burn out your retinas. :) There’s a massive difference between the contrast of that outdoors on a shitty panel (where you’re lucky to get 5:1 contrast) and indoors in a light-controlled environment (where 200:1 contrast is easily reached). And yes, that 200:1 contrast can get painful, especially if you’ve got astigmatism.
- hedora 4y agoI have astigmatism. Contrast isn't an issue. Brightness might be. There are knobs for these on most displays.
- kuschku 4y agoAlternative option: Contrast is only an issue if your monitor is worse than a Fujitsu Siemens P17-2, a monitor from 2004 that nowadays retails for 20 €. If you bought a monitor at any point in the past 18 years that can’t show enough contrast, that’s on you.
- da39a3ee 4y agoI think the trouble is that even educated humans struggle to talk intelligently about medical and psychological problems. We all worry about our health and mortality, and the idea that a psychological or medical condition threatens your life is somewhere between an existential threat, and a worrying cloud over your life. As a result, people easily become wedded to the idea that a particular condition is affecting them, or someone close to them. And they lose their normal objectivity when it comes to swallowing up medical jargon and scientific-sounding names for nebulous psychological / educational phenomena.
- daedalus_f 4y agoI'm from a biology/healthcare background and come to HN for the interesting tech discussions, trivia and the different perspective. I've learnt loads over the past few years and got into a few amateur programming projects in my free time and I'm grateful for that. But I've stopped going to the comments section of anything related to my actual fields of knowledge because the comments are often so wrong/borderline crazy it's hard to know where to start. Makes me wonder if the comments on the tech stuff I don't know so much about are often just as bad but I can't tell...
- savikko 4y agoI have learned here at HN names for lots of effects / phenomena. And started to notice these on my daily life. What you described here is greatly related to The Gell-Mann Amnesia.
- da39a3ee 4y agoOk but I didn't intend my comment to be about HN readers; it's basically educated humans in western anglophone countries I'm criticizing. People just love giving scientific-sounding diagnoses to their problems in their lives, even totally nebulous things like children behaving badly or not doing well academically.
- ciwolsey 4y agoMonitors or anything backlit are terrible to read from for any length of time. Paper or e-ink is superior. I don't see anything wrong with lowering the contrast of text on a screen to compensate for that fact.

- helldritch 4y agoGenerally I prefer a mid-saturation blue-tinted grey in the #111111 horizontal line for my base text colours, which is basically indistinguishable from black but works better with the other hues on our website. That being said, it's easy using the prefers-contrast CSS property to override that to #000000 for people who are hard of sight. It's supported by edge, safari, chrome, opera but it's a bit finnicky in Firefox.
- jraph 4y agoVery much related to my comment [1] two days ago on Please Stop Using Grey Text [2] that says essentially the same thing with more verbiage [1] https://news.ycombinator.com/item?id=31421666 https://news.ycombinator.com/item?id=31421666 [2] https://news.ycombinator.com/item?id=31420938 https://news.ycombinator.com/item?id=31420938 (397 points by marban 1 day ago, 376 comments) - https://tangledweb.xyz/please-stop-using-grey-text-3d3e71acfca8 https://tangledweb.xyz/please-stop-using-grey-text-3d3e71acf...
- waffle_ss 4y agoWhat is the point in linking this? Imagine the mess that comment threads would be if everyone who made similar comments about something did this.
- kingcharles 4y agoI actually really appreciated the comment above. Downvote it if you don't like it. If it gets enough downvotes because the community hates it, then it'll go away.
- waffle_ss 4y agoYou really appreciated a comment that effectively said "hey look I said the same thing two days ago" ...? Yikes dude. Reddit infiltration has totally ruined this place.
- jraph 4y agoCome on, take it easy. I thought that could be helpful. This comment also links to a related, recent story that probably caused this one and that's probably what is most important in this comment. It has been upvoted several times and the person you respond to tells you they found it helpful too. You can't really argue with this. In the past I also linked to comments or stories I've not posted myself and I thought relevant to the context so it's not just me seeking for validation or something. I just like linking connected stuff. I can understand full well how one could find my comment a bit cringy. But please reconsider because what's actually happening is probably not what you think it is. But if you don't, it's fine, I don't really mind. I attempted something, found out that some people liked it (which encourages me to do it again), some don't (which encourages me to be careful not to send the wrong signals - thanks for your feedback), in the end that's expected. Your comment about Reddit, in addition to be outside HN's guidelines, is however totally wrong. I don't frequently browse Reddit, I don't have any account there, that cannot be some Reddit infiltration so I suggest you to consider another analysis. Of this thread of course, but of HN in general.
- eurasiantiger 4y agoThis thinking likely stems from art studies: in classical painting, black is generally taught as one of the forbidden pigments because of ”nothing in nature is black” and, more functionally, because it cannot be used to darken other colors without losing vibrancy and thus a black area cannot smoothly blend to another color.
- simmo9000 4y agoAnd then there was Goya. :)
- hulitu 4y agoAnd nothing is true white so don't use #ffffff. We can continue with blue, green, red. /s
- rob74 4y agoTrue magenta (#f0f) and true cyan (#0ff) are the worst if you ask me...
- Forgeties79 4y agoI’m getting flashbacks to AIM and my putting what could only be described as “neon green” on a black background. But hey, at least it had some contrast I guess?
- wolpoli 4y agoI am sure designers will stop using grey text on solid white as soon as someone shows them that paper isn't really pure white, but is a bit off white and it has texture and gradients, depending on the light source. Maybe they'll start embracing skeuomorphism again. /s
- HPsquared 4y agoOn one of my old phones (Samsung S4), the display would treat pure black differently to dark grey. Pure black would smear across the display when scrolling, a kind of ghosting effect. Probably some effect of the pixels being turned fully off. Dark greys didn't have this effect. I suspect a lot of these "dark grey text" conventions may be related to this hardware issue.
- sp332 4y agoOLED pixels take slightly longer to turn back on from fully off. I remember some VR headsets had trouble with this and they just set the minimum brightness to "1" instead of "0". Edit: note this is per-subpixel, so you need to set some value in each color channel.
- ciwolsey 4y agoPure black and white on a screen is far more fatiguing on a screen than on off a screen so I don't see what's wrong with compensating for that fact.
- jerrygoyal 4y ago> nothing in nature is true black so don’t use #000000” argument.l this comment reminds of the statement made by Jobs about the round corners in the physical world.
- izzydata 4y agoAlright how about #010101 ;)
