It has been discovered that there are mutant women out there who are tetrachromatic, which means that instead of seeing RGB like the rest of us terachromatics, they see in red, green, blue and some color between red and green. However, it appears that their male children are commonly color blind. I thought that was pretty damn cool. Nobody knows how differently they percieve the world, because you can’t really describe a color to someone who’s never seen it before.
