Changing a color for the whole Application

Question

Hi,
Is there a way to change the color, default purple of swing to some other color(say green) for the whole application without using themes? Is it possible through UIManager.put()?
Regards

Thanks Michael,
I just modified your code to fit my needs.
import java.awt.*;
import javax.swing.*;
import java.util.Enumeration;
class ApplicationColor
  public ApplicationColor()
    setApplicationColor(new Color(88, 140, 165));
    JFrame frame = new JFrame();
    frame.setLocation(400,300);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    JPanel jp = new JPanel(new BorderLayout());
    String[] temp = {"abc","123"};
    JComboBox cbo = new JComboBox(temp);
    JButton btn = new JButton("I'm a button");
    jp.add(new JLabel("I'm a label"),BorderLayout.NORTH);
    jp.add(cbo,BorderLayout.CENTER);
    jp.add(btn,BorderLayout.SOUTH);
    frame.getContentPane().add(jp);
    frame.pack();
    frame.setVisible(true);
  public void setApplicationColor(Color color)
    Enumeration enum = UIManager.getDefaults().keys();
    while(enum.hasMoreElements())
      Object key = enum.nextElement();
      Object value = UIManager.get(key);
      Color jfcBlue = new Color(204, 204, 255);
      Color jfcBlue1 = new Color(153, 153, 204);
      if (value instanceof Color)
           if(value.equals(jfcBlue) || value.equals(jfcBlue1)){     
                UIManager.put(key, color);
  public static void main(String[] args){new ApplicationColor();}
