In some situations it makes orientation much easier when even untouched push buttons do
have a solid color instead of having lots of black buttons with just a colored border.
Easiest way in UI would be to give each button (push and toggle) a ‘ON’ and a ‘OFF’ color.
There could also be an option for ‘ON’ and ‘OFF’ text color as sometimes text color is only
readable when button is on OR off.
