I have this amazing plan for my hair, but I'm having trouble figuring out how to make it work. My idea is to have bleached blonde hair [probably like platinum blonde or something], with black lowlights in it, and a couple red streaks in my bangs. I know from experience that putting dark colors on bleached hair doesn't work out very well, and that I should use a semi-permanent color for the black parts, or something like that, but I'm having trouble figuring out how to make the black color stay, if my hair's already bleached white. I know the red shouldn't be too much trouble, because to have bright colors you usually bleach your hair in the first place anyway, right? But the black is what's really troubling me. If anyone could help me figure this out, I'd be totally grateful.

Thanks :]
