All SFX:

Bright as F@#% Yellow
Napalm Orange
Atomic Pink
Virgin Rose
Wildflower

I did a 20 minute 40-volume 1:1:1 bleach wash, and then painted stripes of color from the top of my head on down, angled a bit towards the back. The Wildflower is actually sort of an upside-down teardrop on the back.

It wasn't too hard. Lucky for me, it's a rainbow, and the occasional overlap was harmless. :)

Wow That's really bright! Great job!

That's amazing! I love the colors. They look really good together.

wow...I think I'm blind now AMAZING job

HOLY F$%K! Thats good man, thats a Gallery image right there. Got any more photos and/or any of the process?

That's all I have right now. I mainly took that one to make an avatar with. I'll see if I can get another shot or two tomorrow. It'd be cool to be in the gallery. :) My hair's not very presentable at the moment, though, since I like to leave it unmolested for three days after I finish the process, to give it some time to recover from the bleach.

I never think to take pictures of the process. I will if I refresh it.

Amazing.
If you have any before and can get during photos when you retouch it you could make a really good photo story http://www.haircrazy.info/article/add

wow you rock thats so cool you got to show us how you did it

Meh, I've got a few pale patches, now that I've washed it again. I must not have gotten it on thickly enough this time.

I'll give it a couple of weeks and do it again, with pictures throughout. Stay tuned.

Very well done mix of colors, quite creative!
