Coffee was actually going to be my non-silly response.

I like browns, I think reds are a bit over-done but the reds do look good on you so if you kept your current color you'd be doing fine.

On the other hand, I had purple hair several times, I like it... and it would look nice on you I think. I think if you're under 30 you owe it to yourself to have "differently colored hair" when you can still pull it off... you have a life time to have normal colored hair later.
