This is a joke, right?  Hair color shouldn't even MATTER!  As long as it could realistically happen, which could be anything thanks to hair dying, I could care less what color a girl's hair is.  I just ask that they not change it every so often (like ONE particular girl from Scott Pilgrim VS the World)

Aw come on, just because you have a favorite hair color/style doesn't mean women with other hair types need not apply.
