nice choice, nice choice.
i tried to do mine purple~didn't work out
i did a quick search on photobucket for ya and got some pictures, sure they are not japanese, but i think the style is pretty j-rock worthy, i wasnt sure where you wanted purple so i just went with my tastes, sorry
Purple Bangs/Sidepart
Random Purple Head
that last one is kick ass, get that one!!! if you have the hair for it, that is
good luck next week
