Coach Challenge is a new concept in tennis tournaments which, for the first time, enables amateur players to be coached in real time by their coach. Each element of the graphic identity refers to the fundamentals of tennis: the chromatic range evolves with the seasons and the different playing surfaces, the bounce of the ball is evoked at the heart of the logo's typography, while the ancillary symbols refer to the very nature of the event - the tournament cup, the winning coach's crown, the player's racket. The graphic identity reflects a meticulous attention to proportion: the curves of the ball fit into all the volumes of the typography and iconography.
