I know a bunch of people that are 1/4 black and don’t have blond hair, don’t play games.
So, I know a ton of blondes with kinky frizzy hair. I also have known Indians with tribal registration with blonde hair and blue eyes. And several black people with blue or green eyes
Eye color is controlled by multiple genes. Brown eyed people of mixed parentage can easily produce blue eyed children.
I know a young boy who is 3/4 black or perhaps a little less (I don’t know his father’s complete lineage,although he appears black, but his mother is 1/2 black, 1/2 white with likely some American Indian). This child was born with curly blond hair, practically platinum. He’s now around 11 and he still has blond hair. His skin is also very light.
We used to own a timeshare on Bonaire, NA, where there are many, many families with one blond Dutch parent and one Antillian. Watching these families when they were out to dinner was just amazing: everything from pure straight blonde hair, milky-skinned, blue-eyed to very dark, curly black hair, brown eyed and a lot of mixtures in between.
The Caribbean is full of gorgeous people with brown skins and eyes ranging from turquoise to green and hair ranging from black through blond to reds and browns.
