Great article. Ummm... dumb question, but... stars are colored? (Color blind poster here).
I am not color blind and I've never noticed star colors. They just look white or yellow to me. It must be very subtle.

Is it obvious to everyone else? Do colored dots stand out in the sky? Or is it a subtle thing?
Nice article. Small correction, humans are not old world monkeys (or any kind of monkey). We are apes.
Interesting, so English language has two words for them. e.g. in Polish both are "małpa" (and usually translated to monkey), similar to turtle and tortoise, for us it is a single world "żółw" (and usually translated to turtle).
I didn't know he was color blind. I can't help but connect this to his famous disdain for syntax highlighting and colored text: https://groups.google.com/g/golang-nuts/c/hJHCAaiL0so/m/kG3B...

Anyway, somehow my two friends started looking at color blindness tests. One of them had grown up in Latin America and hadn't seen a color blindness test before, so the other was explaining how there's a number in the center that you can't see if you're color blind. And he said... "what number?" That was how he learned at age 26 that he was color blind.
This is frustrating. He's trying to correct misconceptions and then he immediately gets the word wrong. What he's describing is 'deuteranomaly'. The term 'deuteranopia' applies to the more severe form of colourblindness shown in his diagram (a); it's a form of true dichromacy.

One of them is color maps. I wish people just used brightness maps instead, there's no value added by changing brightness gradient into a hue gradient.
The worst by far are multi-hue gradients.
I'm r/g colorblind, and suddenly the indistinguishability of small colored objects makes sense now. Wow. Okay then. I hate multicolor LEDs with a passion. Those little amber or green dots look identical to me, even when you put them side by side. I use a phone app that uses the camera and shows me RGB values at a reticule. I've gone through rack and racks of equipment with that app, looking for things like dead drive…

I'm also slightly colorblind and pure green light would be harder to distinguish from distance (not critical because there is also light position, but still). That's why traffic lights usually have cyan tint.
This is actually a slightly controversial claim. While r/g color-blind individuals do have difficulty viewing colors, they seem to have an easier time seeing through camouflage:
A study on the ability to distinguish tones of khaki:

There is strong anecdotal evidence that color-blind men specifically recruited during the world wars to see camouflage: (I have personally heard such an anecdote).

And a short YouTube video on the ability of color-blind monkeys to forage for insects, whereas the monkeys with color-vision are better able to find ripe red fruit:

I suspect that if we lived in a world where the color-blind were the majority, it would be those with color-vision who wrote about their 'impairment'. Perhaps with a note about how video games often contain almost-impossible tasks to discern camouflage. (In the real world, video games often contain tasks that require the ability to discern colors that I find difficult due to my r/g colorblindness).
