I agree.

Radim, 
I have patches from Pierre for an RGB-change for *all* display
modules and the patch for the display library. I will send it
to you personally. It was for GRASS 5 beta6. Unfortunately Pierre
seems to have stopped his support. I would be sad, if his work
gets lost.

Perhaps you can take a look at it? Should be almost ready!
