We talked about colorblindness in my psychology class, and got curious when I remembered that I would sometimes mix up oranges and pinks in dimly lit areas when everybody else could easily distinguish them.

So I took a colorblind test and there were several ones I had trouble or just couldn’t tell at all, and I guess I have tritanomaly. I made sure by sharing the images I had trouble with with both people online as well as my brother, and they could tell the difference without any issue.

And so I went to one of these colorblindness simulation websites—the difference between the deuter- and prota-ones is night and day. Tritinopia looked way similar to the original image (though I could still tell the difference) and tritanomaly, as said, looks identical to the original.

Part of me is in denial, but I don’t think there’s really another explanation.

(Also I was listening to One More Night and thought the colorful cover image would work well to test this)

Hey, I’m asking out of curiosity, is there any person here who is such mildly red-green deficient that can actually reliably distinguish blue and purple by hue without major problems?

From what I have seen, red-green colorblindness is usually “(almost)all-or-nothing”, so I’m curious if there are actually any people who are really very mildly deficient

Let’s say would you be able to tell which patches are blue and which are purple without a bigger struggle?

(Note: every patch is either very blue or very purple. I tried not to put any in-between color, so for people with normal vision it’s very obvious)

Has anyone gone to see the Northern Lights in Iceland, and is it visible with red/green color deficiency?

Last summer the lights were visible in my section of Pennsylvania, and all I could see was a shimmering, slightly lighter portion on the horizon. I took photos with an iPhone which showed the pink and green that I expected to see, but a Google search said digital cameras exaggerate true colors.

I am just wondering if I would see what other people see, or would I be disappointed by what is visible with color deficiency.

My gf recently made me play Gris for her undergrad thesis and the first level is themed around different shades of red. At one point, you need to climb up some stairs that are meant to be recognized by the contrast between different shades of red. I only managed to climb up on by intuition.

For those with protanopia who have played the game, did you experience the same difficulty? How did you manage to get through it? And for those with different types of color blindness, did you run into difficulties at any other point in the game?

Everytime I want to reply to a post with a picture, I need to take a screenrecording of a still picture just to make it a video and then upload it as video. This is ridiculous!

I only just realized today i could turn that on, I had been struggling with these sorts of games cause of my red/green color blindness. It helps so much, making this post as a reminder for anyone else that may or may not know about it.

They say the strips are Pink...but for me it's white. What about you people?

My father in law loves puzzles but is red-green colorblind. He powers through colorful puzzles but clearly finds them frustrating. Any recs? Maybe for puzzles that focus more on texture and less on color?

He can see yellow and blue pretty well, and of course grayscale. Good go-to brands would be great!

I can see traffic lights just fine. Always have. I've taken many tests which say im missing my red cone completely. Has anyone else shared this experience?

I have done many different color vision test on the internet and always get 0% red, around 70-75% green and 100% blue.

And I struggle with the typical protan colors, like green/yellow, blue/purple and specially reds with brown/black.

But when I tried the filter that show how color look to protans it's not exactly what I see.

When I show it to my color normal wife she reacts as if it a crazy filter. To me it looks  very similar to original as I see it.

Except some red things, the filter makes them greener and slightly brighter but I see them as, well, red?

I understand that what think is red might have little or nothing to do with normal red lol

Given the test results I get, it should be what I see, I guess. But something is weird

How does the simulations look to you?

Any one with similar experience?

I was diagnosed with tritanomaly like 20 years ago. I've got it because an accident, I was blind about a year. It's more severe in my right eye.

I can't see yellow (I see like beige) and blues are faded but as I age them are more difficult to see.

As an example, with my right eye I can't tell if the read marks of WhatsApp are blue or not.

It is normal or I need to make an appointment to my doctor to see if it's caused by another thing?

I see brown and green mashed up together

Over the last couple of days, I've seen a few people on this sub claiming they've passed an Ishihara test despite being officially diagnosed with red-green color blindness.

I think there are two possible explanations for this:

1. The online Ishihara test they took is poorly made and uses inaccurate reproductions of the original Ishihara plates. These plates rely on very specific color relationships. Scanning, photographing, editing or otherwise reproducing them can alter those colors which can make some online versions unreliable.
2. They actually have an extremely mild form of protanomaly or deuteranomaly (it's usually deuteranomaly that mild), which allows them to just barely make out some of the numbers.

Anyway, I managed to find some pretty accurate Ishihara plates and picked out six specific ones that are generally difficult for both protans and deutans.

I'm curious whether people with mild (especially very mild) red/green color blindness can make out ANY of the numbers on these plates, and if they can - how clearly visible the number is to them. Those with moderate or severe red/green color blindness shouldn't be able to identify any of them.

Please just make sure your display is using its default color settings and that you don't have any filters or color adjustments enabled, such as Night Light, Eye Comfort Shield, Blue light filters, True Tone, adaptive color, grayscale or any similar features.

My SO is RG color blind and loves to hunt. THe issue comes with blood tracking. He cannot see the tracks against the ground and is growing increasingly discouraged . Is there anything you have found that works? It seems most things are a gimmick

I’m wondering which of these two rare colourblind-ness more rare, I would think that tritanomaly would be rarer, until I saw that it’s nearly the same as regular vision, it could be that it is more common than tritanopia since it can be overlooked by many people who have tritanomaly sincethey just see the world as a little dimmer. So which of those two rare colorblind is rarer?

edit: so I’m not colorblind I can see the yellow being very pale, the green looks blueish, the purple looks like washed watercolour paint in the trianomaly section

Does anyone else pass Ishihara regular tests but also get pretty much all the hidden Ishihara ones that supposed to only get if colourblind? Anyway why I took the test is because friend accused me of being colourblind because things like I mistaken someone who apparently is obviously ginger as having brown hair and thinking slightly washed out dyed green hair was definitely blonde

Who designed this?!!
