Ugh. You said it was meant to signal some state, right? I don't know
what exactly you want to do, but are you sure that colour-coding this
info is a good idea? Having more than 3-4 different colours (and always
remember to present the same info by different means, not everyone can
see all the colours) usually adds more confusion than it solves.

AFAIK, there aren't any, but just changing the colour shouldn't be that
hard, pixbuf can be accessed as a simple array of bytes.
