Color Chooser is similar to a MenuButton. When users click on it, a Palette will be displayed so that users can choose the color. You can also set up Style that allows Color Chooser to display interface similar to SplitMenuButton. Note that the Color Chooser is neither a MenuButton nor SplitMenuButton but they is just the same as the interface.
