You made me think about it twice, tbh. I have passed regular vision tests, but never tested for tetrachromacy specifically. I can distinguish 22-35 lines here, depending on how far I sit to ignore jpeg line separating artifacts and how much I unfocus my eyes.
https://kfor.com/news/test-how-many-colors-you-see-can-deter... (so silly to choose jpeg for a color test, oh internet). I don’t think I am a tetrochromat.
I failed another one which asks have you seen this color “before”, but honestly I’ll fail it even on 20 different-hue color palette because I have no color memory and my color vocabulary is on a “3-bit male” side.
Also failed “choose 2 identical out of 4” type. They are all 3+1 unless I peer very hard.
Does it say something?
