JButton "sticking" in a JTable Cell

Question

So I've modified the renderer and what not and slapped a button into a JTable Cell. The assignment requires it to turn red/green altrenativly when pressed. It works perfectly aside from the fact that the buttons appear to not "bounce back" when they switch colors. (i.e. They appear depressed when red and pressed when green). The code is below. any ideas?
import java.awt.Color;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import javax.swing.table.AbstractTableModel;
import javax.swing.JButton;
public class ButtonTableModel extends AbstractTableModel {
     private static final long serialVersionUID = 1;
     private Object[][] rows = new Object[2][1];
     private String[] columns = new String[1];
     public ButtonTableModel() {
          for(int k = 0; k < rows.length; k++) {
               JButton button3 = new JButton("222");
               button3.setSize(200, 200);
               button3.setBackground(Color.red);
               button3.addMouseListener(new ColorChanger(button3));
               rows[k][0] = button3;
          /*button = new JButton("Test Button");
          button.setBackground(Color.red);
          button.addMouseListener(new ColorChanger(button));
          button2 = new JButton("asdf");
          button2.setBackground(Color.red);
          button2.addMouseListener(new ColorChanger(button2));
          rows[0][0] = button;
          rows[1][0] = button2;*/
