Dark purple.
Natural colour is a very ashy dark blonde with whites (I started greying when I was 15!). Before that, it was jet black. I had hennaed with pure henna for about 4 or so years before that, too.
I have brown hair, with natural highlights which I'm very grateful for since I don't have to pay lots of money to have them haha
My mum is a natural redhead. So if I were to ever have children, if the father of those children also had a redhaired gene somewhere, there's a chance my children could have red hair. The ginger flows in me.
