What is the purpose of the libero's uniform?

The purpose of the libero's uniform is to differentiate them from other players on the court. This is crucial for officiating and gameplay, as the libero has a specific role and set of rules regarding their participation in the match. The libero wears a distinct uniform, usually in a contrasting color to their teammates, which helps referees, players, and spectators easily identify them as a specialized defensive player. The role of the libero involves unique responsibilities and restrictions, such as being able to replace any back-row player without prior notice to the officials, which reinforces the need for clear visual differentiation. This uniform notation helps maintain the flow of the game and ensures that the rules regarding the libero's participation are followed.
