public class ColorTilePanel
extends javax.swing.JPanel
implements java.awt.event.MouseListener, java.awt.event.MouseMotionListener

A Panel that shows an array of little colored squares to allow the user to pick a color. By default I use "netscape colors" which are colors that Netscape Navigator (TM) tries to allocate when it starts.
