It depends on your coloring, I think. I'm kind of a warmish-cool, but there are those (like a former girlfriend of mine) on whom blue would just be devestating. Besides, my eyes are green, which lends a nice contrast to the purple. Makes everything pop out.

I used to have a plum celophane on my hair in high school.....

Yeah, my son and I made a deal.... he was going through chemo..... and I they suggested that we shave it so it's less messy when it falls out etc...... usually he buzzed it anyway, but the deal was that if he let me shave it on that particular day..... he could have it any color he wanted when he went back to school..... it was fun, except it didn't stay very long..... I always let the kids have fun with their hair, because once you grow up.... you don't always have the freedom to do those things..... you know?

and he's fine.... and I'd still let him dye it :-)
