This can be achieved by setting the style sheet of the button.

MyButton.setStyleSheet("*:hover {background: green }");

This will control the color just for the button you apply it to.

If you want all the buttons on a form to have the same behaviour, set the style sheet of the widget containing the buttons instead.

MyWidget.setStyleSheet("QPushButton:hover {background: green }");

Style sheets are a very powerful option for customizing the look of your application. You can find more information here.
