Is this why when shown a paint chart from a DIY store women see sunset yellow, royal blue and all manner of crazy things whilst men just see a bunch of yellows that look the same, a bunch of blues that look the same?Ryan Hughes said:Oddly, no known male has ever been tetrachomatic, and it is thought only women can genetically become tetrachomatics.

It didn't take very long, I just started by throwing all the pieces of similar color to each side... once they were next to each other it was easier to differentiate between shades.
