Default button: use appropriate text color

[franksouza183]

There is a problem depending on the type of background chosen for the default button: when we choose the "Use selected background color" option, for example, it does not use the text color of the selections, but common colors. It would be interesting to be able to choose the source of the text color (text color selection, custom, etc.).

example:

The color is gray for the buttons and the text color is black.
The selection color is blue, and the text color is white.

When I use the "Use selected background color" option, text color goes black, not white as it should be.
