Class-spesific colors for self portrait and target portrait

Hello,

Is there any way to change from the standard black-ish color to a color of choosing, ie. orange for Druids, and other classes?

I have included an image so you can see what I mean:

Hmm, there's no way of changing the black background of the Unit Frames to a class color.
