/* 
 * Colors - demo of Swing JColorChooser.
 * Swing's JColorChooser can be used in three ways:
 * <UL><LI>Construct it and place it in a panel;
 * <LI>Call its createDialog() and get a JDialog back
 * <LI>Call its showDialog() and get back the chosen color
 * </UL>
 * <P>We use the last method, as it's the simplest, and is how
 * you'd most likely use it in a real application.
