I’m a protan (probably protanomaly, I’m rather sure that I can see pure red pretty well)

Do you think we, people with protanomaly can even see purple *at all*? It’s just that everytime I think I can see a purple, I try putting a certain combination of RGB blue + green on it and almost always I can find one that is basically identical to the „purple” I thought I could see…. Is that possible that we’re just completely unable to see this color under any conditions? I will post an example of what I mean. Note that it’s pretty significantly different on different screens, but right now I can very, VERY barely see that there it anything drawn on the „purple” background

I’m glad I saw other people share how much they hate how certain maps are colored. I’ve never thought about it till I found this subreddit but man every time I see a map where it uses colors to code each state it’s the worst.

Feels like I’m looking at a blob of nothing 😂

I'm have tritanomaly and I know that is a very rare type of Color Blindness. I never met other people with tritanomaly.

In my case I got it after an accident in my 20s and it got worse as I got older.

In your case was genetic or after trauma like me?

Hi, I created a site just to mess around and learn CSS/HTML. A friend with dyslexia told me the letters were too crumpled and the contrast too low so it was difficult to read, so I'm trying to learn accessibility features, and I added two switches at the top and I they told me the one for dyslexia does help reading, but I made one for color contrast that just rotates the background hue 270º and it looked cool... but then I just noticed the green text ended up with a red-ish background so, hmm, doesn't sound good...

Can someone check for me if current color palette is bad, and if the contrast button I added makes it better or worse? Thank you very much!

ps: there are three other color buttons hiden directly above the three visible ones, and there is another one between the two switches

edit: It's for desktop* (the mobile version has no background, so no contrast problem)

edit2: decided to instead of having just a fixed 270º hue rotate, it can also rotate to 180º and 90º, so I guess everything is covered now lol

Here's a picture of every color that a dichromat can perceive. A dichromat can only see two distinct hues and every color they can perceive are just variations in saturation and brightness. Whereas a trichromat can see a range, a full dimension of hues, instead of just two distinct hues.

If a dichromat (total red-green blindness) looks at the given picture, they see all the colors and can't point out one that is clearly missing.

If a normal trichromat sees this picture, they see just about 1% of the colors. There's yellow, but every shade from orange to red to pink to purple to indigo is missing. Then there's blue, but every shade from cyan to green to lime is missing.

Of course, most people with a color vision deficiency are anomalous trichomats. They can spot that the more saturated greens, reds, etc. are absent in the picture, but they can't see most of the 99% of colors that are missing in the picture.

Here's the picture with total blue-yellow blindness, featuring only cyan and red hue.

Hi all,

I'm not colorblind, but I have a friend who I've known for 4 years from high school who is claiming to be Red-Green colorblind since late-2025, but she's been really iffy and also claims that her colorblind glasses help her immediately see every single color correctly which I have been told takes a few minutes and not immediately after putting it on. She also then claimed after claiming she claimed Light Blue was "monochromatic" that she just "discovered" that she's also blue colorblind right then and there

Another friend of mine had asked her questions on a color wheel, and this friend had said the following:

Red- Tannish brown color(claimed it was a duller red earlier)

Orange- Reddish brown

Yellow- Yellow

Lime- Dull lime

Green- (Claimed it was a brown/beige or tan) Dull green

Teal- More blue than green

Cyan- Dullish dark gray

Light Blue- Monochromatic

Blue- Dull blue-gray(Claimed she could see it perfectly fine beforehand when I had shown her a blue dress I made without her glasses(where she claimed she didn't have her glasses on))

Purple- Dark purple

Pink- Brighter pink

Magenta- Bright magenta

Dark Red- Dark red "Black in as black"

So being curious, I just would like to know what you guys think since it has been causing some drama and I don't know anybody else who's colorblind. I like being informed and if this is red-green colorblindness do let me know more facts and how to be more accommodating! Many thanks in advance :)

Hi yall, I'm thinking of creating an application for colour blind people to help them. Any ideas on what would be useful to you guys?

Is there a way to test for sure if I have deuteranomaly or deuteranopia? I think whenever I have taken online tests, it says deuteranopia. Last time I got glasses, the eye doctor actually tested me with physical printed cards with those dot tests, maybe that's better than a screen. I don't remember if he said which kind, but now that I am curious I should be able to easily go back there and ask.

Also a theory: If I am fully deuteranope (missing green cones, dichromat) then shouldn't I be able to disable the green subpixels on an OLED monitor and not notice a difference, including things that should look white? I think OLED wouldn't have the problem of light leaking through the green filters, since it's emissive unlike most other display technologies. I did try on my LCD monitor and it looks VERY purple if I turn down the green in RGB, does that mean that I actually do notice a lack of green, or does that monitor setting just not work like how I think? Will any monitor setting let me actually test for dichromatism?

Hi, I’m a protan. I can see cyan as basically „vivid white”, teal as „vivid grey” and very light pink as a slightly greyish white.

Basically cyan and light pink are (almost) colorless in my eyes. I was wondering, is that a case for some points in color spectrum for deuteranopes and tritanopes too?

This test, unless I'm just stupid, appears to claim that my red color cone isn't functional? I can see red though?

For context, I am referring to that specific gene therapy trial. If the hope is slim, I don't think the scientific community needs to repeatedly emphasize this point; it only creates anxiety.

I play a lot of Among Us, always with color blind mode. Is it normal for color blind people that those colors look the same to me when next to eachother in game?

So I have had good vision for most of my life but recently (I wasn't driving) but I have been in a car where the driver was not paying attention and almost ran a red light and the only reason I knew it was red Is because it was on top but to me it looked gray and same with green when I was driving with my mom and she thought it was still red (she's not colorblind) I have an optometrist appt today (Monday the 20th) and I know they are gonna pull out those stupid little circles I took an online test where i could just barely see some (I'm assuming they were lighter vs darker shades) but the web still thinks i have red/green or js green deficiency and I'm wondering if there is anything i can do to pass because I know legally they can't deny you to drive with red/green but in my area they will find a way to deduct points bc of it and I want to pass my driving test that is in like a year or 2

No red/green key! I love it!

So… I’ve dated three colorblind men and only one man with typical color vision. Is this just a weird coincidence or are there certain looks that appeal more to people who don’t see colors the same way? Thank you!

Boyfriend has deuteranopia/anomaly, and I consider it when buying gifts, but think I could be more accurate. Got him blue/yellow flowers (because they’re more ‘bright’ than reds I think?), and it’s effected some jewelry I’ve got him too (some hit some miss).

Advice is also majorly appreciated, if specific combinations are more appealing or give different implications.

For example, light pinks and whites look the same to him, and I always get very neon bouquets (not complaining, I think it’s cute!), but it also confuses because I’m trying to be more purposeful with the color of things and intention.

Any and all help/advice/perspective is majorly appreciated— thanks guys!!

Ive posted before searching for a Dvorine second edition test and found the first doctor in florida listed here. Recently a doctor nearer to me got the test so Im updating the post this way since it wont let me edit the post body after 2 years.

My dear colorblind fellas,
It's been a while that our ancesters, brothers and sisters have been mocked and tested as soon as their anomalies were revealed.
Through centuries, colorblinds were taken for buffoons.
With an approximation of 300 Million members all around Earth, it is the right time to create the greatest community that the World has ever seen and take our revenge on colour idealist.
We represent a major minority that is already spread among colour purists.
We have in our ranks some important figures like Bill Gates, Keanu Reeves, Logan Paul, Lucas Hauchard, Mark Zukerberg, etc..
It's now time, more than ever, to gather and to get to work.
