In (3), are you describing what I've sometimes heard called tetrachromat? Is that now confidently considered extant? Last I'd heard, it was an exciting, but only slightly substantiated, theory, but I'd love to see more about it!
- skosuri 10y agoYes, I think you are right. I thought I remember it being heterochromat, but looking online all references seem to be to tetrachromat. In terms of evidence, I think prevalence is there, but there were some papers where they actually tested color perception differences (at least from wikipedia).
- aetherson 10y agoHeterochromia iridum is the condition of having two irises of different colors, you may have blurred the name of that condition with tetrachromacy.
