When did they stop using white balls at Wimbledon?

1986

Why are tennis balls made out of fibrous felt?

Tennis balls are covered in a fibrous felt which modifies their aerodynamic properties, and each has a white curvilinear oval covering it. Modern tennis balls must conform to certain criteria for size, weight, deformation, and bounce criteria to be approved for regulation play.
