What do you call the black lines in a basketball?
The surface of the ball is nearly always divided by "ribs" that are recessed below the surface of the ball in a variety of configurations and are generally a contrasting color.
An orangish surface with black ribs and a possible logo is the traditional color scheme of basketballs but they are sold in various colors. The most famous of these variations, a red/white/blue basketball, was used for the American Basketball Association, the Harlem Globetrotters, and as the "money ball" in the National Basketball Association (NBA) All-Star WeekendThree-Pointint Contest.
