rainmaker-
wsohl & smoref had it correct. Wrestlers are assigned a color for ID purposes as their uniforms may be the same or simlar. The official raises the arm with the color of the scoring wrestler and indicates with his fingers how many points were earned.
As far as the references to Andre, Hulk, etc..., that is entertainment not athletics. Just check out their name, World Wrestling Entertainment (WWE).
