Skin/hair/eye (collectively color) is a trait that can come from the mother or the father. My brother has my fathers skin/hair/eyes. I have my mothers. They are very different. Sometimes the appearing skin/hair/eyes trait is recessive. Two red haired grandfather’s can share a red haired grandson even though neither has a red haired child of their own.
In this case, the blue eyes are recessive, and imply that he has white genes in his DNA. She has blue eyes so both babies have light eyes and light skin in their DNA from her. But they got different color DNA from their father.
I am almost certain that if you looked at his DNA (which you can) you would find he is partially of Caucasian descent.
Neither one is black or white.
