Yes, once again. I suspect the real color of his hair at age 77 is snow white. Not too uncommon for an older person.
When he goes on the road or makes court appearances, he may or may not throw a dash of color in there. That is his call.
My mother doesn’t have a single grey hair, and she is in her 80’s.
Her mother never had any grey hair, and she died in her 90’s. Her father never went grey, but he died in his early 70’s.
So it does happen.
I think he’s going for white. I don’t think he would have shown up with white hair unless that was the look he was going for.
