TIL about Tetrachromacy, a condition which lets you see more colors. Normal people can see about 1 million colors, while tetrachromats may see up to 100 million. Up to 12% of women may have it. (www.healthline.com)

Same with my dad. He said that the military liked red/green colour blindness for spotting camouflaged stuff.

This link is very interesting. Interesting for people that are colorblind, and interesting for people that are not.

I could see 3 out of 4 of them but I'm not colour blind...

That's fun!! I am not color blind and was able with a lot of work to sort of see some of them. The easiest is the second one just squint and unfocus if you wanna try. The first one I couldn't get to work at all though

I am colour blind and the first one was the easiest to see by far. My wife couldn’t make it out even when I showed her where the lines were.

Great, I'm too color blind for the normal tests, and not color blind enough for this apparently. Fuckin dots man.
