I completely agree that it isn't the dominant factor. It still might play some role in selection though. I like blue-eyed girls, and that will certainly increase my offspring's chance of having blue eyes (provided I also carry the gene, of course).

I was thinking more about hair color when I said that, though. And I really don't know what factors cause different hair colors, or what pigments are involved.
