Genetic Question

[D.en.tist to be]

Skin color is a polygenic inheritance. There is 1/64 chance of being a certain skin color. Both parents are heterozygous. What is the amount of different skin colors possible for the two homozygous children?

A) 2 B) 4 C) 6 D) 8

I believe is 2, but someone can explain more.
