LOL I've had blue hair for about a year. Not my whole head, just my bangs and the left side of my face, but it's bright blue, and when I meet new people, they always remember me. XP
Red is also a pretty fun color to have, but you can't really go swimming in chlorine or it will fade to a dull rusty color =( I learned from experience.
I actually had a hair dresser that told me that my hair is "dark-blonde". I considered myself a "brunette", though I guess you could say I'm a dirty blonde.
