Thank you, Button widget focus.

The issue is a little bit more complicated than you might think, as there might simply not be a "color of a button". Some styles on some OSes might use a gradient, an outline or even animate the button on hover/focus/click etc.
That being said you can override the background color of a button when it's focused like this:

yourButton->setStyleSheet("QPushButton:focus {  background-color: red; }");

but be aware that this will disable native styling of the button so on some platforms/themes it will look out of place.
