xbox live tile color

[RevDog]

I've seen several pictures of phones with a black xbox live tile. I can't figure out if I can change mine from the obnoxious Slimer green one. Does anyone know how?

I've never seen the black one, but the green (and Orange) have been XBox (and Live) colors from the start.
