Well, the obvious option would be henna. You only get one color, though, and you can't dye over it (unless you're magic). I also never liked it. It had this really unfortunate thickening effect on my hair, so I kind of looked like Little Orphan Annie for a while.
There are some nice semi-permanents out there (and of course, I cannot provide you with any specific examples because I suck.) Obviously, you're going to encounter some damage, and semi-permanent color isn't going to dramatically alter your color. For example, in the eighth grade, I really wanted to be blonde. My mother bought me a box of SP hair dye, and it turned out red.
Basically, SP dyes coat the hair, and permanents actually lift the cuticle and seep into the little nucleus there.
All that said, you can also check the natural recipes section of the board. They have some good tips on changing your color with things like honey that aren't going to hurt your hair.
