Unnatural hair colors only for white people?

I was just wondering what people thought of people who are dark skinned/tan or black/african american who dye their hair(entire head) unnatural colors such as blue, pink, red(not that red is unnatural..but you know what i mean). I have really tan skin because i am part american indian. although i am considered white. I've always wondered what it would look like if I, or someone with darker skin were to dye their hair an unnatural color. What is your opinion on this? do you think it only looks good on super white people?
