punky hair colour advice?

Question

I have quite dark brown hair. It's fairly strongly highlighted (naturally) and I think the underlying pigment is orange(ish).
Iv'e used temporary hair colours withoout pre-lightening and obviously they don't come out very well, blue looks grey :s.
I have decided to pre-lighten my hair this time and use demi or semi-permanent hair colour (still very bright colours though). I dind't really want to take all the colour out though :(

Basically I'm still a bit confused about the underlying pigment thing. Probablly just feeling tired lol! But am I right in thinking that blues wont work very well because my underlying pigment is orange, so they cancel each other out?
Also, what I was hoping to do was kinda blend from a red) into a purple, bright colours. Will this work well?

Feel free to tell me if you've got any good ideas :D

Answer 1

that underlying pigment thing is aload of crap. i have the same pigment as you and i've been pink, purple, blue, red, green etc.. never been a problem here, as long as you lighten it as much as possible

Answer 2

well, i would leave it, but raquel reed bleaches her hair platinum blond first, then dyes it. It lasts awhile if you use professional stuff. and yes, orange always cancels out blue.

Answer 3

idk.
