Grandson is black and no black people in family?

I'm playing my new Charming Legacy and I'm checking on my various houses. Well one of these houses is my sim-self's sister. She and her husband (who is Blue) just had two grandsons via one of their sons. One of their grandsons, Octavion is black but no one in the family is the same colour. The grandsons' mom's side of the family only have white people in it. The other grandson takes after his dad and Paterneal grandpa blue colour

Its the same in C.A.S playing round with genetics both parents are not black but ended up with a black daughter. But one thing i have noticed is Get To Work there seem to be more black sims now and am happy with that

expect the only thing which is close to black in my family is my sim-self's husband and sister-in-law and they're suppose to be Native Americans. So techinally not back

Maybe your sims husband should be keeping a closer eye on his wife ;o)
Hardy har har.
In my games recently (since I started having blue folks) I've noticed more skin color variations with their children. Perhaps when they have blue skin, their skin color becomes a toss up? I mean, it wouldn't make sense but perhaps it's a glitch to be ironed out. (Example, I had a light skinned, blonde haired father married to a blue woman...they had twins, one was blue, the other had very tanned, dark brown skin. Maybe my blue woman is a mexican alien! ;o)

Luckily you can just do the cas.fulleditmode and make the child whatever skin tone you'd prefer.
