How must a pitcher’s glove be colored?

A pitcher’s glove must be a color that does not interfere with the ability to see the ball, which is why it is stipulated that it can be any color except white or gray. These colors could blend into the baseball and make it difficult for the batter and the umpire to see the ball during pitching. The rule is designed to maintain visibility and fairness in the game.

The other responses suggest different restrictions, such as matching team colors, wearing natural leather colors, or using a transparent glove, which are not specified as requirements in the rules. While team colors can influence the overall aesthetic of uniforms, they are not mandated for the glove specifically. Additionally, allowing natural leather colors would not always address visibility concerns, and the requirement for a transparent glove does not exist in standard regulations. Thus, the correct understanding of the rule focuses specifically on excluding colors that might blend with the baseball.
