изменить цвет лабиринта с JSlider в java swing

Question

Как мне изменить цвет метки в java swing. Во время работы цвет ярлыка меняется между красным и синим цветом через каждые 200 миллисекунд. Когда я перемещаю ползунок, интервал изменения цвета метки обновляется и равен значению jslider. Но мой код не работает. Кто-нибудь, помогите мне, пожалуйста, спасибо. Вот мой код.

public class AOutcome extends javax.swing.JFrame {

/**
 * Creates new form AOutcome
 */
public AOutcome() {
    initComponents();
   // jlbColor.setOpaque(true);
}

/**
 * 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.
