For instance in my family, my great-great grandmother had blue eyes and dirty blonde hair (her parents were Belgiums) while my great-great grandfather had dark haired and brown eyes.
It took all the way till the 3rd generation for someone to get her hair and eye color. It seems like once they get married to someone with the dominant genes, that color is already hard to get and can skip a whole or couple generations.
