The “color-set” signal

void
user_function (GtkColorButton *widget,
               gpointer        user_data)

The ::color-set signal is emitted when the user selects a color. When handling this signal, use gtk_color_button_get_color() and gtk_color_button_get_alpha() to find out which color was just selected.
