I'm just gonna' be a noob & say, "red cuz its da colour ov blood!!!! lololololooooo!!!!" Seriously though, it is red. So yeah... ¬¬
Colour/color may be chosen... I don't really have one favourite colour/color in particular, but I do like most kinds of green. It's simple, yet natural, and you can mix it with eiter blu or yellow, to mak it energic or tired.
Has to be something sinister, like black. But in this fucked up community I can't say that for racism. Ok, white. That's better.
