DW's family has a lot of both dark skin and light due to several mixed relatives. DW's sister looks very much like my sister's kids whose dad is Choctaw. My sister and I are part Cherokee and Apache.
DW and Mr W have full epicanthic folds and are both very fair. Mr W gets some stares esp from Chinese because he is fair and blue eyed and looks very Chinese in his eyes.
One of my classmates in HS had blonde hair and blue eyes and very chocolate skin due to her mixed heritage. Two of my nephews are the same way. It's very striking.
They get a bit of guff from pure whites and indians over it, but I had them look up "hybrid vigor" and we discussed what it meant.
