I used red, blue, and purple, but it's hard to see anything except the red in my picture. What's really important here though is that now I have a way to color my hair whenever I'm gonna go out on the town. So instead of painting the town red, I can paint my hair. No big deal.
Next time I'll have a little better idea of exactly what color I'm going to put where, tonight was mostly an experiment. And plus, if you hate it, you can just wash it out. Or brush it out.
