Background colors in pallets

I would love to have the option of being able customize the background color of the pallet windows. This would be particularly useful in color pallets as it would give more of a visual look to the pallet. Example red pallets could have a red background. The best would be if it could represent the color chosen automatically.

In other pallets it could also be useful. Beam pallets could easily recognized as which gobo wheel they are controlling. IE. all wheel one would be blue and all wheel 2 red.

Key stroke could be pig+set to change background color.
