I don’t know if I’ve already told you this: I’m color blind.
My color blindness isn’t severe (I’m not seeing the world in black and white, and I can actually get right even some “advanced” nuances, such as lilac or fuchsia), but nonetheless here and there it pops up, especially related to green/brown and blue/purple mix and matches.
It’s not like I ever forget being color blind, but playing a bit with an old game for iPad (Forever Lost is its name, a clunky, quirky escape room/puzzle game) I was reminded how frustrating it is for a color-impaired person to try and solve incredibly easy puzzles just because the game designer thought it was a good idea to base at least one third of the game on riddles that rely on the ability to discern bright green from yellow in a very small pixelated area.
