Europeans uniquely have diverse hair colors from black to red and eye colors from brown to blue due to sexual selection. Most humans have black hair, brown eyes, brown skin. Color diversity arose from many new alleles at separate genes for hair (MC1R), eyes (HERC2-OCA2), skin (SLC45A2 etc.). Selection favored brightness and novelty producing color polymorphism. New colors spread until common then declined as another novel one arose. Europeans have 11 nonsynonymous MC1R alleles vs 5 Asian and 1 African. Diversity stronger in women than men for both hair and eyes. Women outnumbered men on mate market due to low polygyny and high male hunting mortality. Intensity increased at higher latitudes where women provided little food. Strongest on ice-age steppe-tundra of northern/eastern Europe. Ancient DNA shows early Europeans had brown skin but non-brown eyes. Skin whitened via sexual selection for female paleness not UV or vitamin D. Blue-eyed men have more feminine faces. Women post-puberty lighter-skinned than men universally. European color traits evolved rapidly post-40,000 years ago via selection not drift. Hair/eye diversity preceded skin whitening. Face shape feminized via same selection. European women have enhanced sexual dimorphisms like wider hips narrower waists.
