I bleached out an oval on the top of my head and the rest of the front. I dyed it pillarbox red from manic panic.
The rest I just redyed MP aftermidnight blue.
There's a little bit of a weird purple mix I made from MP ultra violet, Raw Purple Passion, MP cotton candy, MP vampire red, and SFX blood red. It doesn't show, but you can sort of tell there's a purpley tone in there.

Nice! I like the effect you get as your hair fans out.

Nice resulting color, and also like how the red spreads out from the front to the back. A very nice idea in my humble opinion.
