Communication is achieved by coloring various sections of the surface of the ball with different colors that mix and form new colors when the ball is spun. Preferably, the colored sections are three mutually perpendicular great circles and, preferably, the different colors are the primary colors, red, blue, and yellow. For a golfer, the intersections of the great circles can be used as a focus spot in hitting the ball. Individual great circles can be used to align the ball with the target and the golfer with the ball and also as an aide in putting.Field of SearchGame ball-carried indicia | |
