I prefer bright epic colors. The first time I dyed my hair, I dyed it purple. Then pink. Then black, which is still here... I'm waiting for most of it to get out before I dye it again. My next dye choice : Rainbow! :D
When I was a teen I used to. Now, I'm all grown up and can't do that crap anymore. Back then, I had every color of the ranbow. It was even camoflauged at one point.
It can seriously damage your hair if you do it regularly. I like the idea a lot and I kinda want to do it, but I don't want to hurt my hair. I'll probably color it when I am an old woman with a full head of gray hair.
Black and purple.
I color it burgundy.
PINK
