Change Fill color when shape is drawn

I need to figure out a way in which if the user draws a complete shape the fill color of the shape would change color. In other words if the user complete a circle it goes from being an outline or a shape to a solid colored shape.
ideas?

To get this to work efficiently, you'd need coding which isn't available in GS. Sorry to disappoint you.
