Create your own by subclassing the AbstractColorChooserPanel class.
To add a new panel to the existing set, call: public void addChooserPanel(AbstractColorChooserPanel panel)
To remove it: public AbstractColorChooserPanel removeChooserPanel(AbstractColorChooserPanel panel)
To replace the existing set of panels: setChooserPanels(AbstractColorChooserPanel panels[ ])
