Confused on the hair colours....

I think it's supposed to be like a combo of their hair colors, like the silver lightens the brown to make blond

Also the mother-in-law has blonde hair too and father0in0laws hair is not as silver as the siblings

Yeah it’s probably a combination, the grandparents have pretty light hair as well. Honestly hair color can be pretty weird. My mothers blonde and my father has black hair but I’m a dark blonde. Meanwhile my younger sister is a brunette.


Another example is my mother being a blonde while both her parents had dark hair and dark eyes. She got her hair colors from her grandfather. She’s the only blonde with green eyes of her siblings, her brothers have black hair and brown eyes.

Indeed.
