There are some interesting reconstructions here..apart from the blond Richard, which (try as I will) I just cannot accept. If he’d been blond (especially THAT blond!) it would surely have shown on his portraits. Or comment would have been made. His hair was medium-brown to dark, maybe a shade of chestnut…just NOT blond!
It seems the genetic results show that he was probably blond as a child, but darkened as he grew older. Well, I can go along with that because the same applied to me. My hair was like a cornfield when I was small, then went a darkish nondescript shade of mouse. Now, in my dotage, it’s gone almost white again! In fact, I’m the natural colour now that I once paid hairdressers fortunes to achieve. No justice!
