The ::color-set signal is emitted when the user selects a color.
When handling this signal, use Color.buttonGetRgba to
find out which color was just selected.
Note that this signal is only emitted when the user
changes the color. If you need to react to programmatic color changes
as well, use the notify::color signal.
