Is there a rule book that says a certain hair color is for one specific race?
All he is saying is that it looks bad. He never said they couldn't have it.
I have rarely seen a black chick who actually looked better with blonde hair. It just looks bad with their skin color, just like jet black hair usually looks bad on a ginger.
As for her skin getting lighter....
She was already light skinned.
Sometimes, yeah, she looks lighter/darker. Blonde hair on some people washes out their skin color. I have had just about every hair color you could imagine. It makes a difference with your skin. Some colours make me look completely washed out and dull.
She could also have gotten darker from, you know, performing on stage outside in the summer or going on a vacation and spending it on a beach or a boat like a lot of celebrities do.
It also depends on the make up used on her, the lighting, the color shirt she is wearing....certain colors I wear make me look a lot different than others. Colors work with your skin tone.
^From last week, clearly darker for obvious reasons.
