Do you mean you dyed it black, but there's a tint of pink within it? Eg. If you're in the light, it shines pink?

If so, I think a lot of people would probably like it lol.
If it's full on blatant pink then perhaps not.

Dye it again but with a different hair dye? Or perhaps at the hairdressers?
Should sort things out =]
