Change colour of a circle whether mousePressed is an even or odd number

Question

Right this is sort've difficult to explain. I have implemented a grid of circles for a Connect 4 game with the help of you fine people :) Now to add to this, I am looking to change the colour of a circle depending on whether it's an even or odd mousePressed. Basically this is like playing somebody else, so each player takes it in turns. If there is an easier way to do this then I would greatly appreciate it.
public class CircleGrid extends JPanel implements MouseListener
        boolean ifRed;
        public CircleGrid()
          ifRed = true;
          addMouseListener(this);
        public void toggleColor()
          ifRed = !ifRed;
          repaint();
        public void paintComponent(Graphics g)
          if (ifRed)
            g.setColor(Color.RED);
          else
            g.setColor(Color.BLUE);
          g.fillOval(0, 0, 50, 50);
        public void mousePressed(MouseEvent evt)
           toggleColor();
        public void mouseClicked(MouseEvent evt)
        public void mouseReleased(MouseEvent evt)
        public void mouseEntered(MouseEvent evt)
        public void mouseExited(MouseEvent evt)
     }That is the code which draws the ovals and such on to my gameCenter JPanel.
I was thinking something like:
pesudo code --
if mousePressed is an even number
then set g.setColor = blue
else
g.setColor = red
Thank you guys. I would appreciate any help. I'm still very much a newbie and some of my questions, I'm sure, are trivial to most of you but we all have to start somewhere.

Hey LW, cheers buddy. :)
I used your idea.
Here's my working code:
if (clicks == 0)
                    ifRed = true;
                    repaint();
                    clicks = 1;
               else if (clicks > 0)
                    ifRed = false;
                    repaint();
                    clicks = 0;
               }
