i think you already know, but if not:
there are human tetrachromats, they are rare
all women
because women get two copies of genes related to vision which are on the sex chromosomes: XX, while men get one copy: XY. so only women can get one normal gene, and one with a mutation that shifts one of the three cones, thus giving them tetrachromacy
normal people can see 1-10 million colors, such rare women can see 100 million or more

@benroyce @jamesmarshall @leaverou So, they see 10x the color data, they see it _without_ added tech, and why do I have a suspicion that they still get labeled as "inferior".

@benroyce I don’t like the word “superhuman” in the title. She is a human, isn’t she? @jamesmarshall @leaverou
