DEADLY RAVE

A smug smarty pants gets hypnotized into becoming a cut-loose, neon-clad raver.  While this isn't in color, she also may have dyed her hair some neon color, even though this is Anime-style and all improbable hair colors can be in effect. 

Strangely, she's still wearing her usual pair of glasses instead of having traded  them in for something far more showy, though it may have been because the party responsible for this change preferred that  part of her old look.

Also, yeah... Mirror Ball earrings.
