RE: tennis balls
"By rule of tennis law—specifically, the International Tennis Federation, or ITF—a tennis ball should be yellow in color. The edict was handed down in 1972, after television viewers had trouble following the movement of white balls. Manufacturers like Gamma Sports also identify their product as yellow—in Gamma’s case, optic yellow."
