As for Tiy having red hair...c’mon! We’ve all seen plenty of depictions of her. She was twice as African as 0bama.
Isn’t it said that many mummies have red hair because the stuff that makes it brown or black will fade with time, faster than the stuff that makes it red? (So that most mummy hair gets redder with time.)
Either that or there’s something in the human psyche that urges folks to mummify redheads, because there sure are a lot of them in the mummy population.
