I had a dark haired tribe who somehow got a blonde in one generation and another blonde in the next generation. I bred the two several times and got more blondes. Many generations later they seem to be mostly red-haired.
Another one of my tribes had mixed hair color, but then somehow got very dark hair - haven't seen a blonde or red-head in several weeks.
I tried to breed an all blonde group, but darn! We got some strangers and the breeding mom when for the dark haired man while I was sleeping.
