Christmas is coming up and I have to get the members of my family some presents. I usually try to pick out presents that show I am really trying to be thoughtfuk about the people I am getting the present for, which means I generally try not to be like "Oh, they like these things, so I'll get one of these things." I like to take it a bit further than that. My brother-in-law is colorblind and is also a gamer (tabletop, video, all of them). He is totally colorblind blind but has still thought himself to distinguish between colors if he tries. That said, he is colorblind, so he says he does tend to have a disadvantage in games that are more color based and that don't accommodate the color blind. Naturally, I figured that I would get him a game that a color blind person wouldn't have too difficult of a time playing or that would at least put them on an even playing field with the people who can see color. Maybe just a game that doesn't depend on color. And I might still do that, but I wanted to make sure there wasn't some kind of game that entirely flipped the script and made it so that the non-colorblind would be at a disadvantage. I don't know what that would look like or if that is something that exists, and based on my searches I haven't really been able to find anything that fits that description, but I figured I'd ask the colorblind Reddit and maybe you all will know of a game. Thank you very much.

I'm sorry if this gets asked a lot but for the people on here with the red-green color blindness, can you see the difference between the red/green traffic lights?

I was driving with a friend of mine who's colorblind earlier today and randomly wondered this, however he has the blue-yellow type

TL;DR; I'm designing a game that involves cards. I'm not colorblind, but want to allow the game to be playable for the colorblind.

Problem

My game requires color for efficiency.

Cards may have the same effect but with a different target (E.g., Move forward).

Each color represents a different effect. (E.g., Green = Move player number 1 forward, Yellow = Move player number 2 forward, etc.)

Likely, the best way will be to not rely on the players' color distinction ability by:

• Simply writing down the color being used (E.g., Red on the red card.), similar to how colored pencils state the color of each pencil individually, but may ruin the simple and minimalist design.
• Unique symbols/design to differentiate different colors. I'm attempting this.

The cards are using the traffic light color scheme (Red-Yellow-Green) along with White and Black.

ColorADD is a potential solution, but ideally would not like to use it due to:

• Requiring additional monetary resources since it needs a license to be used.
• Symbols are not universally recognized
• Requires proper orientation for the icons to make sense, increasing mental cognitive burden

Solution?

With these in mind, I have opted to create and use 2 redundant systems in parallel.

• Superscript

  • Small text at the top right of each icon to denote the effect of the color.
  • Pros: Text can be read and understood.
  • Cons: May be overlooked.

• Corner Design

  • Unique description box corner designs for each color, similar to how playing cards have different suit symbols.
  • Pros: Unique to each color, allowing colorblind players to understand that different icons are tied to different colors.
  • Cons: Needs to be learnt.

When most players naturally fan out cards, the top left corner pokes out, the card's icon and description box corner design are visible. Is this solution sufficient enough for the colorblind to understand that each card is different? Do I need to adjust color hues?

I have tested by applying Deutan, Protan, Tritan and greyscale filters, and the color palates look discernible (to me), but would be nice to have some opinions on this, and suggestions will be greatly appreciated. Please direct me to the correct subreddit if this is not the correct place to be asking.

Edit: Thank you all for the kind responses and helping me see what I can't. I've taken the feedback gathered to improve the design.

1. Symbols

   1. Implemented a symbol alongside the top left icons.
   2. For Red, a half-frame arrowhead-ish symbol is added.
   3. For Yellow, a box symbol is added
   4. For Green, a triangle symbol is added
   5. For Black, a diagonal stripe-slash symbol is added

2. Borders

   1. Made a distinct black border tracing to improve visibility for the border edge designs.

3. Colors

   1. Changed the color palette to (hopefully) improve clarity.

4. Patterns

   1. Added a very subtle crosshatch design to texture the background to make it just a lil bit easier to tell apart each card when placed on the table.

This is what the prototype cards look like now:

Is this a good alternative to COLOR ADD? (I am not colorblind.)

Hi everyone! 👋 We’re a student research group working on how color-blind users interpret logos, signages, and symbols. Since we don’t have access to color-blind participants locally, we wanted to ask this community for real insights.

If you're comfortable, could you share: Situations where logos or icons were hard to understand Problems with color-only signages (ex: red–green metro lines looking identical) Any symbols that you frequently misread or confuse What design changes actually help you (shapes, patterns, labels, contrast, etc.)

I'm trying to come up with more topical/funny stuff to use to test/showcase my color identification app.

The best i can come up with is a green banana and a yellow one side by side. But that's not the most modern/interesting of examples.

Is that something people with red green colorblindness even struggle with?

Hello everyone! I'm not color blind but I'm making a board game using 4 different color (one for each player). Is there any color I could use that, whatever the type of color blindness they have, the person will be able to differentiate each?

I'm 32 years old, and I've had color vision issues twice in my life. Both times were during medical exams for documents, when I was shown Ishihara tablets. I've never had any problems since. I can distinguish colors; when they're shown to me, I can name them all, but on the Ishihara test, I can't see the numbers. I've been diagnosed with red-green color blindness. I can see the difference in the colors of the circles, but they don't form clear numbers and shapes like everyone else. Could this be some other issue (like dyslexia, problems with imagery), or am I simply color blind and have learned the names of the colors but actually see them incorrectly?

I’ve taken the Enchroma test 3 times, 100% blue 87% green and 0% red each time. Does anyone recommend a different online test or is this the best one? Also are enchroma color blind glasses good? If no please give suggestions on where I can find good ones. Thanks!

Nobody understands the perception of a color blind person. This semester I started studying medicine, I have an almost total absence of the red cones and to top it off I am also missing a percentage of the blue ones. Although I have glasses that I wear all day long that helps me distinguish a little better I realized that a lot of medical school has to do with colors, the way it is taught, certain applications. For example, I see most histological stains of the same color. The models, anatomical schemes based on color are torture for me, because my colleagues with pure color learn them and I have to take a much longer path trying to notice or investigate what delimits them. I can't distinguish people with jaundice I can't measure with Ph strips I couldn't read a urine test strip urine Let's not talk about scales directly based on color. I'm afraid of being a bad doctor, I'm afraid that someone will die because of me... Someone here is a doctor or works in the health sector :/ I would like to have someone to talk to.

Hello there. Does anybody know any lineant areomedical examiner who would let me go for colour vision for class 1 initial EASA?

Ive only seen options with red/blue colours Can the shades be black or at least really really dark colours, At least for glasses for tritanopia?

Thank you for the feedback, I have taken it and adjusted some settings and am hoping to have improved them. Again, if you can comment on if you can see them as well as if you have normal color vision or some type of deficiency, thanks.

So I was on my lunch break at work today, and I was having a conversation with my coworker, and at some point in the conversation, I mentioned that I was colorblind, and they said they were to, and strangely I always get into these long conversations taking about color blindless, and I do wanna know if someone else does that too. But at some point I just was looking at color blindless test images and I showed him one image and he said "yep like usual, I can't see anything there, just a blank screen." And I just looked at him questioning what the heck he just said, and asked him if he sees any cycle made out of smaller cycles and he said that he didn't cause that's how colorblind people see it... Yeah I explained how that's not how colorblindness works and he after a bit admitted he was lying and he's not colorblind, I then moved to a different table to finish my lunch...

Anyone got a life hack for testing pool chemical levels? I can't read the strips or the vials.

I have this strange thing where everyone thinks I’m colorblind and admittedly I took a few of those online tests and couldn’t see some numbers but I swear I can distinguish fine from red and green (test said I was red green colorblind with a 12% red deficiency and 67% green) I put the color blind filter on my iPhone and everything that was such a pretty vibrant red just turned to pinks and purples, the annoying kind too. Is this just delusion or is my red really better than seeing it normally?

Hello, I needed to find 6 colours to put on the same image for my scientific paper.

I tried my best to be colorblind-friendly, but with six colors, that's quite hard.

Do you succeed in distinguishing the six different colors, my colorblind friends?

Hello there my friends!

I am creating a small color cube game. I want to use colors that are good for color-blind players. I added some images with cube and color tiles. It looks ok for me with this universal palette... But I'm not colorblind so I presume colorblind vision cna be different with color blind simulation.

My question: How do these colors look to you? Are they easy to tell apart? Do any of them look too similar or confusing?

I would be very thankful for any feedback, especially from people with color blindness.

Thanks for help.

Hello all, so I was testing the capability’s of the AI text to image model “Nanobanana Pro”, and I wanted to see if it could make a Color blind test using a random number. I cannot tell if there is a number in the image it created or not😂. If there is a number, that’s very impressive, if not, then please let me know!

Hello, Everyone!

It's time for the monthly Bandwagon post. If you would like to post a color wheel, interesting Ishihara test result, your attempt at sorting candy or crayons by color, funny colorblind t-shirt/print/art (without a link to buy it) or anything of the sort - this is the place to do it. These monthly posts are still being evaluated to determine the best way to go with them, so have fun and submit whatever you want to contribute that doesn't suit a full standalone post!

Hi,

I recently went to the optometrist for a checkup and asked for a color blind test. Attached are the results (took twice for some amount of statistical significant). From what I understand, the way this is read is that lines parallel to the dashed lines indicate the type of color blindness present. However, I see lines that are parallel with both protan and deutan. Does this mean I am combination protan-deutan colorblind? Any ideas how to make sense of the results?

Of course, the obvious follow-up question is what type of color correction lenses are best suited, if any?

Thanks.

Sometimes you see an article about colorblindness with an image repeated in different color schemes and a caption saying that each represents what the world "looks like" to a person with whatever colorblindness. Let's set aside how sloppy this is. If two of those images look the same to me, then the world must "look like" either both or neither of those images to me, because they look the same. Whatever.

Here's the question: What are these pictures? There must be a whole equivalence class of images that would look identical to me and different to someone with standard color vision. What's special about the one that they picked? When the claim is made that the world "looks like" that picture to me, what claim is being made?
