A tennis ball is a ball designed for the sport of tennis. Tennis balls are fluorescent yellow in organised competitions,[1][2] but in recreational play other colors are also used. Tennis balls are covered in a fibrous felt, which modifies their aerodynamic properties, and each has a white curvilinear oval covering it.
