Why Did Television Turn Tennis Balls Yellow?

For much of tennis history, balls were white or black. Their color was selected to contrast with the court, not to satisfy the needs of television cameras.

As televised tennis expanded during the 1960s and early 1970s, the ball presented a problem. A fast moving white object could become difficult to follow on a television screen, particularly when it crossed white court markings or entered areas of changing brightness. Color broadcasting created an opportunity to test a more visible alternative.

The International Lawn Tennis Federation conducted experiments and concluded that a bright yellow ball was easier for television viewers to track. In 1972, the federation added yellow balls to the official rules. The selected shade became known as optic yellow, although viewers still sometimes disagree over whether it looks more yellow or green.

The change was not immediate everywhere. Wimbledon, famous for preserving its traditions, continued using white balls for another fourteen years. It finally adopted yellow balls in 1986. Today, white remains permitted under international rules, but optic yellow dominates professional competition.

The color was chosen primarily for people who were not standing beside the court. Players could already see the traditional ball, but the growing audience watching through cameras needed greater contrast.

One of the most familiar objects in modern sport therefore acquired its signature appearance because television had become part of the game. The ball was redesigned not only to travel across the net, but also to remain visible after passing through a screen.
