None of my bikes are actually purple.

(Well, the hybrid is, but I never ride it so it's more of a dirty, heavy ornament than a bike.)
Black is a nice colour for bikes: not only does it show the dirt less, it blends perfectly with reflective tape, which is always fun. Only done the seat stays so far, but I have plans for more. And spoke lights.
