This widget looks like a GtkComboBox and it displays a list of preset colour shades. These patterns are defined by colour parameters, see Shade.
This widget can emit a "shade-selected" signal that is a wrapper around the "changed" signal, but it is emitted only when a new shade is selected and this shade is passed to the callback.
