My natural color is probably the most boring thing ever, just a mousy brown... from what I remember. I've been dying it since I was 11, and I'm 24 now. It's been every color under the sun except for green, I think. Since I'm all "grown up" now, in other words, my company will only allow certain colors, I've been sticking with a very dark brown. Plays up my pale skin and blue eyes.
Thinking about dying it back red, though. I just wish that it would't fade so quicky.
