This callback is called by the NamePicker
widget whenever the user picks a color by name. The
argument is a Color object representing
the selected color. It passes the new color to the .set() method of the Adjuster
widget, so the new color can be shown there. See Section 15.2, “Adjuster.set(): Change the color”.
