Nope! Even vampires would have to get tired and bored being broody and 'blood lusty' all the time, and always wearing dark colours! Have to do something bright and cheerful every once and a while. The black clothing has to stay though. Better for stealthily tagging the local streets with their graffiti! "Vlad waz 'ere!" and "Real vamps don't sparkle!" or "AB+ FTW!" would be some good slogans.
You have to wonder though... when do vampires, with an eternity stretching out before them, suffer their mid-life crisis and attempt to recapture their youth? Maybe it happens every 100 years or so?
