A two colored baseball or softball for practice. One half of the outer surface is a dark color and one half is light to make the ball more difficult to see than a standard ball. When used for practice, the ball requires players to concentrate intensely in order to hit or field it successfully because of the difficulty of seeing it clearly. During games when a light colored ball is used, it is much more visible and players are able to hit and field it better because they are used to practicing with the two colored practice ball.
