Blue. Had to be primary blue.
Because I am an anime fan.
Because I have blue eyes.
Because I like blue.
Because everyone does their hair red.

Of course, since it was dark blond before, I had to bleach it -- but the effect is great. If I could have an injection or get my DNA modified to make my hair blue I would. The only pisser would be that here in Cambridge you might as well walk around with your dick hanging out for the kind of reaction you get from a lot of normal people. The upshot, people talk to you about it, and it gets a reaction from cute girls, that is the kind of girl I find cute...

It's also kinda cool shedding blue hair about the place...
