    I am making a game with only a few fixed colors:
    • Background
    • Floor
    • Hazards
    • Collectibles
    • Interactables
    • Accent (A colour that is meant to magnify the level's themes, safe to set to the same colour as the floor)

    Even before I watched this talk, I wanted these colours to be freely changeable, not just with unlockable palettes, but with a full-on colour picker.

    I originally just intended this feature to changing the contrast to something more intense when the sun is shining on the screen and maximizing the brightness isn't enough, and decreasing the contrast for better colours in darker rooms.

  2. Sosasees Posted on July 17, 2020 at 12:06 pm

    It takes a lot of effort to preview all the images with all the colorblind filters. But it only takes a little effort to preview them with just one of them.
    So, is it enough to only use the Full-on Greyscale filter?

    Key steps for supporting colour-blindness

    . Don't just communicate with color.

    . Understand your palette/color features.

    . Use preview tools.

    . Colour-preset system.

    . Think about wide-reaching solutions.

    . Test with colour-blind players/colleagues.

    . Make your accessibility options accessible!

    . Ask for community feedback.
    We are #yolostudiogame on twitter – an indie game studio with two members.
    We are seriously learning about the game industry.
    So we tweet a GDC video summary every Tuesday.

    Happy making game, everyone!

    One of the coolest thing with the boardgame Ticket To Ride is how the colorblind-aid symbols to help you match train cards to train tracks, are also modestly decorative, making the visual design of the game better for everyone.

  5. Alex Chhay Posted on July 17, 2020 at 12:06 pm

    That dress is fun for me because I am one of the people who it switches for so it's fun to try to see it the other color.

  6. Asobi tech Posted on July 17, 2020 at 12:06 pm

    What a wonderful clear concise talk, with actionable solutions. Excellent work Douglas Pennant.

  7. Valden Posted on July 17, 2020 at 12:06 pm

    Kolorblind has apparently transitioned.

  8. Robledo Gonzalez Posted on July 17, 2020 at 12:06 pm

    I just discovery that I really can’t say either when someone is blushing!

  9. KAY B 14 Posted on July 17, 2020 at 12:06 pm

    schrödinger's hair 😀 😀

  10. Michael Kulin Posted on July 17, 2020 at 12:06 pm

    An actual in-depth talk about color-blindness unlike that ~10-15 min crap by Game Maker's (not) Toolkit.
    I don't know why I even bothered mentioning this man.
    Anyway, this was an informative monologue regarding color-blindness. 🙂

  11. Soy Milk Posted on July 17, 2020 at 12:06 pm

    This is amazing
    Thanks a lot for sharing

  12. ankimo Posted on July 17, 2020 at 12:06 pm

    Great presentation! I really love how he talk slow and clearly. Really helps me listening while working!

  13. erin collective Posted on July 17, 2020 at 12:06 pm

    i really want to learn what you're teaching but god damn the cognitive dissonance is huge when you keep refering to chromosomes as if they belong to specific genders, please inform yourself about gender studies, genetic divination regarding "men and women" harms trans people

  14. Mimu Mi Posted on July 17, 2020 at 12:06 pm

    I watched the video the other day and I just wanted to add something. I can't remember exactly, but I think the speaker was saying at some point that there was a lack of systems to assist the colorblind in general.

    Well first, use your smartphone when you can. There are many apps that can give you color value from a photo, or possibly even in real time through the camera. RGB values in hexa or percentage, it may help. Better than nothing.

    Secondly, there is this one standard that I find very clever
    I can't even remember if I ever saw it "in the wild", but this is typically the kind of accessibility feature that should be made more popular.

  15. Torito Games Posted on July 17, 2020 at 12:06 pm

    31:16 Exactly what I am doing in my game, creating a colorblind friendly palette for my game and to distinguish enemies from friends. Of course this is easy as colorblind solo developer 🙂

  16. nutritional yeast Posted on July 17, 2020 at 12:06 pm

    subtitles help me because I have trouble processing audio and speech due in part to ADHD. accessibility stuff like this helps audiences you wouldn't even expect, or undiagnosed audiences

  17. Aleksandras Tvardauskas Posted on July 17, 2020 at 12:06 pm

    Very informative. Thank you for sharing it. The only thing I am missing in this talk is how to design multiplayer competitive games (such as Fortnite) for color blind people when distinguishing colors is part of your game design. If part of your gameplay is to find a camouflaged enemy hiding in bushes and enabling color blind mode will make the enemy more visible for everyone, the majority of hardcore players will have the mode always enabled for the competitive advantage. In this case, you will end up with many players playing a less colorful version of your game, with those playing the game as intended being in a competitive disadvantage.

    It is very important to make your game accessible to as many people as possible, there is no doubt in that. But the main question is how to make it happen when your competitive gameplay is based on testing who can distinguish colors better etc.? How to make it accessible without giving the competitive advantage for those who are not in a need of the extra accessibility?

    Eating uncooked food? Being lefthanded shortens my life…

  19. Meowium99 Posted on July 17, 2020 at 12:06 pm

    Yes! I'm an advocate for Video game accessibility! Colourblind features are extremely helpful and honestly should be thought about early on as to not cause headaches later on in development.

  20. ZoidbergForPresident Posted on July 17, 2020 at 12:06 pm

    The most interesting talk I've ever seen on daltonism.

  21. Jeef Berky Posted on July 17, 2020 at 12:06 pm

    I didn't realize how many people were colorblind, you'd think such a hefty amount of people would be tempting for studios, there's money to be made there

  22. Twisted Logic Posted on July 17, 2020 at 12:06 pm

    I can't play puzzle games like Puyo-Puyo due to my colorblindness (and none of the colorblindness modes ever seem to help). Friends of mine never really seem to quite understand and get offended when I don't want to play such games with them

  23. Deshara Posted on July 17, 2020 at 12:06 pm

    Call of Duty has always been completely unplayable for me, it's literally a game of distinguishing actors from a background made of brown which enemies blend into which 1 in 8 men are physically incapable of doing

  24. Lunareon Posted on July 17, 2020 at 12:06 pm

    Excellent talk, thank you for demonstrating the problems so clearly. I would also second that you should just let the players adjust the colors themselves, because that would solve the problem for more people. Most games already let you customize controls and audio, so why not colors as well. The more people can enjoy video games the better. 🙂

  25. Daniela A Posted on July 17, 2020 at 12:06 pm

    Thank you so much for this presentation! I am actually developing a game and I'm trying to do it color blindness friendly without it being a secondary option. I have no idea if I am being successful but at least this video has given me a clearer lead. So far, I think my color selection works and I'm excited to reach the point where I could test it with real color blind betas! Thank you again!

  26. LCwavesAtYa Posted on July 17, 2020 at 12:06 pm

    Ok, so I've had people call me a twat but I am still seeing that dress as gold and bluish-white. I now know it's blue and black but I am still seeing gold and white. You know what? YOU, YOU ARE ALL TWATS!

  27. Unknow0059 Posted on July 17, 2020 at 12:06 pm

    this guy seems like such a nice guy
    3:20 why is the white in the centermost area of the yellow section, and not any other colors?
    seeing only two colors must suck so much…
    16:37 no, don't bring it back! ahhh!!
    very informative talk, as someone who doesn't know.

  28. Relptica Posted on July 17, 2020 at 12:06 pm

    Fascinating talk. Haven't really thought about struggles colour blind people encounter in games before.

  29. AoiKaze2000 Posted on July 17, 2020 at 12:06 pm

    The game is not Total War:Warhammer, it is Total Warhammer…..

  30. Gawayne Posted on July 17, 2020 at 12:06 pm

    There is something that turns red in braking zones??

  31. D G Posted on July 17, 2020 at 12:06 pm

    For anyone unaware, Windows 10 has colour blind filters build in at the system level. It can be turned on in the Settings / Ease of Access. As I am not colour blind I'm not sure how useful it is though.

  32. Ether Pump Posted on July 17, 2020 at 12:06 pm

    Great talk. The speaker is clearly comfortable and has pleasant voice, rhythm and are very clear.

  33. TimmacTR Posted on July 17, 2020 at 12:06 pm

    Great presentation! Masterfully explained. I now "see" the problem more clearly thanks to you 🙂

    Though, I just hope we find solutions that involve voluntary implementation, 3rd party solutions and education rather than government-imposed sanctions which would be unfair to smaller devs.

  34. IDontWannaChooseAName Posted on July 17, 2020 at 12:06 pm

    As someone with deuteranomaly I can only say "defect my ass". It's the rest of the world which are khaki- night- and shapeblind.

  35. BdR76 Posted on July 17, 2020 at 12:06 pm

    32:40 Excellent talk, I always thought Bejeweled solved this so elegantly, using both colors and shapes.

  36. Deft3 Studio. Posted on July 17, 2020 at 12:06 pm

    I was always and still am curious about making games available for a wider audience, I'm very happy about this video.

  37. Aaron Canaday Posted on July 17, 2020 at 12:06 pm

    Great lecture!! It's nice having accessibility in games becoming a more common conversation among players and devs.

  38. Tired_David Posted on July 17, 2020 at 12:06 pm

    This was one of the most educational sessions from GDC 2019. I'd love to see developers place more emphasis on UX in regards to accessibility; this does not come at a prohibitive cost (neither time nor funding) and should become one of the first items tackled by every art director.

  39. Dekunutcase Posted on July 17, 2020 at 12:06 pm

    One thing that is underrated is to desaturate your palette before settling on it. If everything looks the same, your contrasts aren't different enough for even non-colorblind people. Using different saturation levels can also solve a lot of the problems (not all of them) for the ones who are color blind, like in those puzzle games. If two colors are similar, but one is much darker, you can still tell they are different.

  40. ReddoFreddo Posted on July 17, 2020 at 12:06 pm

    Color blind friendly features should be something that's mandated by law, because it's not that much work to fix it and it would be a huge game changer (no pun intended) for a lot of people.
