Want a new color but what do do???

Well if you want it orange, pop some bleach on that baby and your good to go! Granted, it will look horrible.

Before you doing anything, though, you're going to have to get the black out of it. Try a colour removing/stripping product so you can start again. But I wouldn't do this if your hair's in bad shape, it might fall out. Apply the colour you want over top, maybe a light honey brown?

Good luck with it.
