/* 
 * 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>
 * <li>Call its createDialog() and get a JDialog back;</li>
 * <li>Call its showDialog() and get back the chosen color.</li>
 * </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.
