As I mentioned in my previous post, when I recently began a new set of families, I was going to try to keep them each within a hair color scheme. This particular family was intended to be a blonde family. As you can see, my initial couple were clearly blonde. However, there only child has darker hair. When it came time for him to marry, I chose a blonde lady. For some reason, they are producing red-headed children.

Incidentally, I know there is a head chart available in this game, but I'm not that "into" the game to study it out and plan my people by it. I will take my chances and be surprised. And I truly am surprised how this family went from bright blonde to bright red.
