Changing JOptionPane background color based on If statement

I would like to change the background color of a JOptionPane message based on an If statement. If a user hits one button, a green message background would come up otherwise a red one will. With the following code, both messages come up one after the other. What am I doing wrong? Thank you

if (e.getSource() == cmdYes)
                 new UIManager();
            UIManager.put("OptionPane.background",new   ColorUIResource(0,255,0));
             UIManager.put("Panel.background",new ColorUIResource(0,255,0));
                JOptionPane.showMessageDialog(null, "Green Message", 
                        "Green", 
                        JOptionPane.INFORMATION_MESSAGE);

            if (e.getSource() == cmdNo)
                 new UIManager();
            UIManager.put("OptionPane.background",new ColorUIResource(255,0,0));
             UIManager.put("Panel.background",new ColorUIResource(255,0,0));
                JOptionPane.showMessageDialog(null, "Red Message", 
                        "Red", 
                        JOptionPane.INFORMATION_MESSAGE);
