What color can a towel be during a game?

The correct choice allows for a level of specificity in the guidelines governing the equipment used during a game. A towel that is a solid color other than white serves a practical purpose, ensuring that it does not interfere with the game's visibility or create confusion on the field. The restriction against white is particularly important as white towels could be mistaken for a penalty flag, which could disrupt the flow of the game and create misunderstandings between players, officials, and spectators.

Team colors typically refer to uniform aspects such as jerseys and helmets, while allowing for any color including patterns could lead to inconsistencies and potential confusion. Therefore, the selection of a solid color other than white strikes a balance between providing teams the flexibility to use towels while maintaining clarity and order on the field.
