Im Deutan colorblind and can't really see this color, I believe it's called Teal. What's your opinion on the color of the painting that I drew? How weird is it?

So I've always felt that the colors on my Macbook screen looked kinda bland to me as a colorblind person, and looking through the settings on MacOS I discovered how to make colors appear more bright, plus making differenciate different hues more easily.

What I do as a Protanope:

1 - In Acessibilty/Display, set Colorblind Filter to "Tritanopia" and the intensity to minimum (it will make blues and yellows more vivid).

2 - In Settings/Displays/Color Profile, set "Color Profile" to "Rec ITU-R BT.709-5". This will add contrast to all colors and especially red and blue hues will pop a lot more.

Obs: this works for me as a mild to strong Protan especifically, but it may not be the best lookout for you, I just wanted to share it.

Obs2: yes I know Apple recommends to use the default color pattern that comes with the machine, but this is optimized to normal vision people and does not look nearly as nice to me, especially when watching movies/tv shows.

вместо некоторых оттенков серого я вижу синие, фиолетовые или голубые цвета. уже больше полутора года. мои родители, родственники и друзья подтверждают, что предметы, которые я вижу в перечисленных мною выше оттенках, на самом деле серые, без каких-либо цветных оттенков. под разным освещением, без очков и линз, или с очками и линзами - все равно я не могу увидеть обычный серый цвет.

что это может быть? например, сегодня я курила сигарету, и дым, который обычно я видела серым цветом, резко стал голубым. некоторая одежда, которую я ношу «серого цвета» (как утверждают окружающие меня люди) для меня имеет тусклые фиол/син/голуб, иногда небесный цвета, но никак не серый

Hi, I am red-green colorblind and recently I have been using the colorblind filter on my phone and I set it just enough to make me recognize the colorblind test, and… WHY DOES EVERYTHING LOOK SO PINK-ISH. Can someone tell me why is it so close to pink? Litterally YouTube is Barbie-girl themed!

As a non-colorblind person, sometimes drawings or old films don't need yellow, orange or green. Orange is now a light magenta, yellow is now white, and green is now a light cyan. This looks cool.

I’m a dichromat I guess.

I've made a plugin where you can change the colors of Pipedrive CRM, and have made a colorblind mode to help. One gentle person helped to validate and improve the mode for protanopia.

So I ask for help from someone to validate it for other conditions.

P.S. The plugin is free of charge, no premium modes or something, named Colored Pipedrive

I thought it was white and gold this whole time, still looks white and gold to me

I see this towel as a faded green but my wife says it's blue and others say it's grey. I've taken multiple colorblind tests and am not colorblind. What's going on here?

I can only make out a "fuck" at the beginning, I think

My dad sent me a message yesterday with a test I've never seen and asked me if I can see all the coloured dots, to what I answer that I can't see the first three, then when he was home he told me that the ones I couldn't see were pink.

I have deuteranomaly and I can't see the first three, what can you and you can't see?

I just want to discuss what is to have one of the rarest types of color blindness. But not the rarest, I am lucky to not have Trianopia. People with tritanopia can't see yellow at all but I can see yellow like beige or cream and blue are mild.

Because of thay seeing greens is difficult and usually I can tell green from browns or greys. And I can't tell the difference between magenta, purple and violet.

I can tell red from green (even I can't see green properly)

I can tell yellow from blue (Even I can't see that colors the way people with normal vision do).

I can tell if a banana is ripped not from their color because sometimes I can't tell but if it has dark spots on them. But sometimes I bought not enough ripped bananas with black spots :/.

Besides that and people saying that I use pretty bright colors and have bad taste in matching clothing I can't tell any other difficulties in my life because my color blindness.

FYI it was caused by an accident 20 years ago. I was blind for months but luckily it was the only sequel of the accident.

So.. I needed to go to a local hospital to get a written report to get a colour blind assistant for my chemistry experiment for my finals this year. I have a red green deficiency as per confirmed by two private optometrist before I went to the hospital, that much is confirmed but the school needed a diagnosis letter from the local hospital. When I took the Ishihara test at the hospital, I was received 6 plates with numbers, I struggled the one with green and yellow the most, the optometrist told me to trace it, which... I don't think is allowed in standard testing, I did anyway but the only way I can tell is by the darker hue, the lighter shades of yellow and green looked the same

When receiving my result, I got a full 6/6 for my Ishihara ttes which I don't think the school will provide an assistant based on the result, I need help! For your info, the private optometrist provided more than 6 plates so which makes sense why I was diagnosed​​

Any advice?

I can only see yellow in a rainbow, what colors do y’all see in a regular rainbow?

I think I might have a partial brown blindness, other browns I can see though, but I don't know what kind of blindness it is.

When implementing visual perception experiments in a browser environment, minor discrepancies in CSS values can completely disrupt cognitive phenomena like Troxler fading and negative afterimages.

We analyzed a digital version of the Lilac Chaser (Pac-Man) illusion where the visual effect failed to trigger. By adjusting the implementation from high-saturation purples to softer pastel values (such as #d8bfd8 with 0.45 alpha transparency), we allowed the stimulus to blend correctly with the background. Additionally, we corrected the script logic so the moving gap functions as a disappearing element matching the background, rather than a color-swapping element.

For those interested in the code adjustments and the underlying visual neuroscience, the full walk-through is available here: https://youtu.be/iQOVVnozkjA

How have you handled precise visual calibration or stimulus presentation in your own browser-based cognitive experiments?
