What makes a uniform bottom illegal?

A uniform bottom is considered illegal if it is a different color from the rest of the team because teams are required to have a cohesive look that promotes unity and identification during competition. The uniformity of color helps referees, coaches, and spectators quickly identify players on the same team. Additionally, having a consistent color scheme avoids any confusion that may arise during play, as uniforms are part of the sport's regulations aiming for clarity and organization on the court.

While design consistency and the absence of logos might be issues in some contexts, the primary violation regarding the bottom specifically hinges on having a different color from the rest of the team's uniforms. This ensures that all players are clearly identifiable as part of the same team, maintaining the integrity and professionalism of the game.
