         frame= new JFrame();
         JPanel panel = new JPanel();
         button = new JButton("Show color Palette");
         text1 = new JTextField(20);
         text2 = new JTextField(20);

         panel.add(text1);
         panel.add(text2);
         panel.add(chooser);
         chooser.setVisible(false);
         button.setLocation(800,600);
         button.setActionCommand("");
         button.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent ae) {
             color = chooser.showDialog(chooser, "SHOW THE COLOR", chooser.getColor());

              if(color!= null)
               {
                 String hex = Integer.toHexString(color.getRGB() & 0xffffff);
                 hex="#"+hex;
                 text1.setText(hex);
               }
             }
       }
             });
         frame.setVisible(true);
         frame.setSize(1000,800);
         }
        public static void main( String [] argv)
       {
         Main m1 = new Main();
       m1.process();
      }
    }
    </pre></code>

Most colors don't have something like a name. Your mapping would only work from the other side.
