    is this brown square background the correct button background behaviour?

    Oops, bit ugly...
    I think this will need to call JPanel#setOpaque(false):
    JPanel p2 = new JPanel() {
    @Override public void paintComponent(Graphics g) {
    g.setColor(new Color(100,50,50,100));
    g.fillRect(0,0,getWidth(), getHeight());
    }
    };
    p2.setOpaque(false);
