Went to the hairdresser today, and right before I was going to get my hair shampooed, I inquired about streaking my hair blue. Much to my surprise, she just so happened to have blue dye lying around.
It's not the color I wanted, but I dunno if I would be able to really find that. In any case, it'll lighten up in the first couple washes I do and then generally fade.
This is about the best picture I can manage for now.
