Using `get-panel-background' to get the button color might work well

Probably controls that support bitmap labels should also support mask
bitmaps. Maybe in v202.

As Daniel said, it sounds like you want to use the classes defined in
the "hierlist" collection. (I know. It's not easy to find if you don't
know it's there.)
