What kind of listener do I need? pass an ActionEvent?

Question

How do I add a listener to ColorChooser? Everytime ColorChooser generates a Color I want to pass the Color to the JFrame setBackground(). Exactly once colorChooser1PropertyChange in the JFrame will do this, but it only does it once.
Somehow, I need to setup a listener but I'm not quite sure how nor what kind. I'm vaguely thinking that an ActionEvent could help here, but I'm not positive. I think that ColorChooser needs to pass an event of some kind, and then the JFrame needs to set up a listener to grab the event.
I'll revisit the Sun tutorial, but would greatly appreciate guidance :)
The ColorChooser is the heart, this is a javabean:
package a00720398.util;
import java.awt.Color;
public class ColorChooser extends javax.swing.JPanel {
    private Color color = new Color(0, 0, 0);
    /** Creates new form ColorChooser */
    public ColorChooser() {
        initComponents();
    /** This method is called from within the constructor to
     * initialize the form.
     * WARNING: Do NOT modify this code. The content of this method is
     * always regenerated by the Form Editor.
    private void initComponents() {
        red = new javax.swing.JSlider();
        green = new javax.swing.JSlider();
        blue = new javax.swing.JSlider();
        setLayout(new java.awt.GridLayout(3, 1));
        red.setMaximum(255);
        red.addChangeListener(new javax.swing.event.ChangeListener() {
            public void stateChanged(javax.swing.event.ChangeEvent evt) {
                redStateChanged(evt);
        add(red);
        green.setMaximum(255);
        green.addChangeListener(new javax.swing.event.ChangeListener() {
            public void stateChanged(javax.swing.event.ChangeEvent evt) {
                greenStateChanged(evt);
        add(green);
        blue.setMaximum(255);
        blue.addChangeListener(new javax.swing.event.ChangeListener() {
            public void stateChanged(javax.swing.event.ChangeEvent evt) {
                blueStateChanged(evt);
        add(blue);
    private void redStateChanged(javax.swing.event.ChangeEvent evt) {                                
        //System.out.println(setColor().toString());
        setColor();
    private void greenStateChanged(javax.swing.event.ChangeEvent evt) {
        //System.out.println(setColor().toString());
        setColor();
    private void blueStateChanged(javax.swing.event.ChangeEvent evt) {
        //System.out.println(setColor().toString());
        setColor();
    public void setColor() {
        color = new Color(red.getValue(), green.getValue(), blue.getValue());
        System.out.println(color);
    public Color getColor() {
        return color;
    // Variables declaration - do not modify
    private javax.swing.JSlider blue;
    private javax.swing.JSlider green;
