A few things to note here. It is comparing deuteranomaly to protanopia. The first is anomalous trichromacy, the latter dichromacy - meaning the first type has all three cone types but one is malfunctioning, the latter is completely missing a (different) cone type. So this is not really a good comparison.

Second, as far as I know, no good anomalous trichromacy simulations exist. They all work by (usually linearly) interpolating between normal vision and dichromacy, but this is not supported by empirical evidence.

Third, this does not seem to take into account the lightness differences caused by missing cones.

Finally, while there are multiple types of “total colourblindness”, most if not all suffer from severe acuity problems as well, and usually many other vision problems. The final picture is very unrealistic.

It still visually conveys the fact that there are different types of colorblindness and a rough approximation of the differences in a way that is understandable to the general population even if it isn't 100% accurate.

It is high level, like "mammals don't lay eggs".

I agree - I wish it were more accurate, but anything raising awareness is nice.

The deuteranopia has to be at least somewhat accurate because it looks exactly the same as the “normal” picture to me. I know that the nature of malformations in the cones means that other people with deuteranopia will see it slightly differently too, but for me this seems spot on.

I also have deuteranopia and the top two look similar but I can clearly see the orange, red, pink on the right. I’ve never understood these diagrams and think they’re nonsense.

I’ve always been a little confused about it too because I seem to have trouble with reds, but every time I take a color blindness test they just tell me I’m weak on greens. It’s weird.

To me, the first 3 do look the same.

But I have a diagnosis that explains it.

So stupid they only make this meme for people that can see all colors, why don't they also make one for colorblind people, so they can see what non-colorblind people see!?

I'm pretty sure I don't have color blindness. But that's how I knew I had shit vision.

Someone pointed to a sign in a distance. I said, "Lol stop fucking with me. There's no sign." And everyone in the group gasp that I couldn't see it.

Yeah magic mushrooms will do that

Tritanopia probably looks kinda cool

[-] [email protected] 3 points 1 month ago

I have a friend with that type. He said he mostly sees shades of red. Graphs and charts are very hard for him to interpret.

[-] Zehzin 4 points 1 month ago

My color blind friends have the opposite problem (no reds) but they also complain about graphs and charts.

tritaniopiacs, untie! /s

I've always been a bit fascinated by colorblindness. To me, a "normal"-seeing person, green and red are so VASTLY different that mistaking them feels so bizarre to me.

Would human blood look the same as xenomorph blood? This suggests it would.
