There are lots of color schemes available for colorblind people. Most of these are made for websites and regular user interface components, but I'm sure you can adept them to games as well. That way you can make it not only practical but also balanced and good looking for colorblind people. If you have a complex UI in your game, I would definitely look into that.
Talking about examples, I have a bad one: Final Fantasy XIV. Some colors, like the ones used to mark quest areas on the map, are super hard for me to see. They have different color-blind modes tho, and they all _just slap a filter on the whole screen._ Please, don't do this. If sth looks like a green tree to you, it'll look like a green tree to me, even when the color I see is different from your green. It's still the color of the trees outside. What I need is the UI colors to change.
I might be able to write a shader that does exactly that for you! My next video is about fixing ff14's graphics and I can see about making a shader that only hue shifts the UI.
rather than hue shifting everything, would something akin to what adobe lightroom does be better? it basically lets you change the hue/sat/value of an entire image but only for certain colors.
Someone asked me to add colorblind support for my game. Without this video I would probably just mistakenly implemented a filter that simulates colorblindness instead, very pog video
@@Acerola_tBy the way my personal syntax highlighting theme was deliberately designed to utilize as many different hues as possible, it's literally unusable for colorblind people at least according to colorblind filters, bruh
@@Acerola_t Oh, also what I meant by "mistakenly implemented a filter that simulates colorblindness" is that some developers would slap a colorblind filter in their game and call it "colorblindness mode" which is very misleading, almost did the same because of how prevalent that phenomenon is
I asked this in a subreddit and got downvoted/ didn’t get a straight answer: Why do games/ apps need to implement color blind modes individually; is there not a way for the OS or monitor to apply it’s own filter to the final image? Your videos are awesome btw 👍
Generally it's best to selectively change UI elements for usability, like League does. One option for sure is just hue shifting the entire render into a range that could be seen by color blind people, which is certainly possible to do for games that don't have color blindness options with something like ReShade (uh oh spoiler for next video).
@@anthonysilveira6181 I read somewhere that they did a survey of color blind people and they preferred the selective UI changes, but I don't know where I read that lol
@@anthonysilveira6181 If you change the entire image then it'll just plain look weird. Blue grass and red skies would look totally unnatural even to a colour blind person. To them it'd just look weird in a different way.
AMD video cards, at least my one, have a "Color Deficiency Correction" option that can be applied per monitor. It gives you three sliders labeled Protanopia, Deuteranopia and Tritanopia that you can just experiment with. Of course it's not as good as changing game art but it sure helps for me. imo the best option is things like when Among Us added shapes to the wire task.
My dad is colobrind, so much so that reds and greens look identical to him. And he's in the printing business which is a big disadvantage apparently, but my mom acts a correction factor as she double checks all the colors before printing anything. Anyway, doing this check before releasing the game makes it much more playable for ~10% of your audience which is potentially a huge factor. Thanks for bringing this issue into the spotlight and providing us with a simple shader to check whether or not our games suffer from it.
As a gamer and artist with some level of deuteranomaly, this insightful video was genuinely helpful in visualizing how the cones in my eyes fail to function properly sometimes.
Great video! Fun fact, the amount of men that are colorblind is significantly higher than the amount of women (1 in 12 men vs 1 in 200 women). I released a puzzle game on Xbox a couple years ago and it never occurred to me to add a colorblind mode until the reviews started coming in. Shifting colors isn't the only approach to fixing the issue. I went with adding glyphs and icons to the various sprites to differentiate them.
Acerola, your videos are so interesting and informative. I'd love to see a video created by you that explores water in video games; the rendering, physics, optimization etc. of it.
Another accessibility issue is lack of ability to seperate the speech from almost same-volume music and ambient - in games, but also in video with non-content-oriented sound mixing. It was hard for me to focus on your good and insightful explanations because of that.
I was playing Minecraft with my friends and he said redstone looked black. I went over an confirmed it was infact red. That was the day he found out he was colorblind
If you watch the video at X2 it just sounds like a A list of all the terrible things that could happen whenever you take medicine you hear on commercials from news channels
This is such a good explanation! This is all fairly unintuitive at a glance, and easily available explanations severely lack detail, so as someone who recently ran into their first colorblindness accessibility issue at work a few weeks ago, this is a fantastic and highly-appreciated resource.
Yay I'm 7% of the population. I have pretty severe deuteranomaly (reduced sensitivity to green.) I always describe it as my greens being shifted towards yellow and red. Or simply as "muddy yellow." So when you describe the findings of this paper as shifting the sensitivity function. It matches my personal findings, lol.
Weird! I was always under the impression that M cones contributed the most to our perception of brightness, because of how camera sensors have 2x the number of green pixels and screens often have 2x the number of green pixels. Thought that the sensors and cameras were doing that to replicate our sensitivity to green. But I must have been missing or misunderstanding something.
Great video! However, just because you have eyeballs doesn't mean you can see colour like... at all. Fun fact, for people wondering: yes, monochromacy (also called achromatopsia) exists, where the person basically seen in grey scale.
I hate color blind modes that apply an automatic filter, they either barely work or don't help at all (deuteranomaly). Tip for developers, you can't possibly come up with filters that work for everyone. Simply allow us to change the color of important UI or game elements ourselves, it doesn't even need to be an in game option, an editable config file allowing changing of the RGB values per element is more then enough. NB: To work out if a game/UI element is 'important', make all instances of that element have the same color, if that makes the game hard/impossible, its important.
I have some kind of Deuteranomaly and when you changed League to simulate colorblindness, it actually made them just a tinier bit easier to tell apart for some reason lol
Wait, I thought I had Prota color blindness but the comparisons you showed tell me otherwise. I noticed the difference between the two sides for Prota, but for Deutera I didn't. I guess I'm part of the majority then (and that you can't trust internet tests very much lol). Great video. Oh, and also, Danganronpa 2 IS my favorite game of the DR franchise, nice choice!
Funny, I think a colorblind person might sometimes prefer things to not to be corrected as that is how they interpret the world on an every day basis. For example they see grass the same way the game is attempting to display grass. If you correct the game grass for colorblindness then you are showing them something they are not familiar with as grass. It is a little complex. But as you said it is definitely useful to correct color for competitive play.
To stop anyone else having a crisis at 2am - if tritanopia looks the same, make sure your phone isn’t in night shift otherwise they look very similar xD
If you want to be even more specific, the L cones don't allow us to see red, but rather interpret longer wavelengths as "RED", the m cones interpret medium wavelengths as "GREEN", and S Cones interpret short wavelengths as "BLUE" (or ultraviolet[Humans can naturally see "Ultraviolet" -> 300nm wavelengths but we have a lens to protect against it, but some people are born without it/get it removed because of eye surgery and never get them replaced]) Colors are a machination of the brain. (Which invokes the idea that everyone might see color, not slightly different, but WILDLY different, since color is simply a neurological interpretation of the wavelength of electromagnetic rays, we could assume that what you see as red I might see COMPLETELY different, or as another color.)
Even more wild than that, different cones have quite an overlap so the colors we call "red" or "green" we actually "see" as mixtures and just interpret them as clear colors. So if for some reason you could trigger the cones separately you would be able to see red several times "more red" and green much more green. I suppose some drugs might be able to get this effect...
The funniest and saddest thing for me is that due to this stuff I didn't manage to make good 3d models consistently. The shape has always been alright but making a color scheme is a total stumbling block for me. Almost every time I made a 3d model I would show it to my pals and they would say that it is indeed cool but the color is off and strange. And, of course, asking every time whether the color is ok or not is not the best thing to do, so I completely gave up on doing this
Hi there, your comment made me think. Have you considered focusing on value instead of hue, like painters do? You can make it an aesthetic instead of a limitation, I'm sure! The video "Are your colors boring? Try this digital painting exercise!" by Marco Bucci (Thank you RUclips for making clickbait titles necessary...) shows pretty well how unimportant actual colors are, as long as the values are correct. The other option would be to stay in grayscale, and there are a lot of aesthetics to go for, not just dark and gritty Film Noir. I hope you'll find a way to do what you love despite the hurdles! :)
