Salutations,
You asked this question about 3 months ago, and no one answered it.. How rude of them, well....
You can customize any control/indicator by right mouse clicking on it, going to advanced, then customize. If you want to color it, you can always right mouse click with the shift key down, and pull up the painting tool stuff. Or use the tab key if you want to scroll through tools. I believe it's the tab key. Alright, i bet you've long since figured it out, but i couldn't resist.
Sincerely,
ElSmitho
