Displaying multiple colors in a shape?

Question

Hi i have made a game where users click on the screen and a red triangle appears correspinding to where they clicked. How do make the game act so that when i/user clicks on the screen the user would see for example the colours red, blue, green, yellow in that order in each triangle. Would i need to use the Cardlayout functionality ? if not, how?
The code for it to be red is as follows;
if(m_bMouse)
               gc.setColor(Color.RED);
                    for( int i = 0; i < m_nTrianglesDrawn; i++)
                         gc.fillPolygon( m_polyTriangleArr);
                         m_bMouse = false;

Suggestion:
1. Start small. Create a subclass of JComponent with a shape on it that cycles through a sequence of colors, driven by a javax.swing.Timer. You can either have the timer never stop, or have the timer stop itself at the end of the color sequence.
2. Have the component start out empty and add the shape when the mouse is clicked on the component. That click starts the timer.
3. Allow for many shapes on the component rather that at most one.
Do one step at a time, so that you can debug and test as you go along.
