It would be nice to be able to dynamicaly set different colors for different DIGITS within one PANEL.
Would be usefull when button texts are strings represented in DIGITS, for changing the color for the over-state.

I agree. It would make it much easier to have the color of numbers represent a status, whitout using a lot of panels.
It's ok to have different panels for different kind of information, but I would like to keep digits in the same one, because it's easier to align them etc...
