Hi Randy,

I'm a bit unsure if it helps you, but you can simply subclass 
/RectanglePortrayal2D/ directly with /CoordinationPlayers/, something 
like the following code (haven't tested).

This way you'll have a /color/ variable (called /paint/) by default.

    public class CoordinationPlayer
             extends RectanglePortrayal2D
             implements Steppable {

         private static final double DIAMETER = 6.0;

         public CoordinationPlayer() {
             super(DIAMETER);
             paint = (random.nextInt(2) == 0) ? Color.RED : Color.YELLOW;
         }

         ...
    }

This way you don't need the magic in the /setupPortroyals()/ function.

HTH,
Richard
