The Surprising Story Behind One of Sport’s Most Recognisable Colours
It’s one of those things we rarely think about.
Tennis balls are yellow. They’ve always been yellow… right?
Actually, no.
For much of tennis history, tennis balls were white.
The move to the now-famous “optic yellow” ball is one of the most interesting examples of how technology changed sport—and it involves one of Britain’s most famous broadcasters.
The Original Tennis Ball
For decades, tennis was played using white balls.
They worked perfectly well for players and spectators watching courtside. However, as television became increasingly important in the 1960s, a problem emerged.
Viewers at home often struggled to follow the ball on screen.
This became particularly apparent with the introduction of colour television.
Enter David Attenborough
Long before becoming the world’s most recognisable natural historian, Sir David Attenborough was a senior executive at the BBC.
He played a significant role in launching colour television in the United Kingdom and was heavily involved in improving how programmes appeared on screen.
As televised sport became more popular, Attenborough recognised that white tennis balls were difficult for audiences to see.
Research was conducted to determine which colour provided the best visibility on television, and the winner was a bright fluorescent yellow-green colour that became known as “optic yellow”.
The Official Change
In 1972, the International Tennis Federation approved yellow tennis balls for official competition.
The decision was primarily driven by television audiences rather than players.
The goal was simple: make the ball easier to see.
Today it seems obvious, but at the time it represented a significant change to one of tennis’s longest-standing traditions.
Wimbledon Held Out
Not everyone embraced the change immediately.
Wimbledon, famous for its traditions, continued using white tennis balls long after other tournaments had switched.
It wasn’t until 1986 that Wimbledon finally adopted yellow balls.
Today it’s difficult to imagine Centre Court without them.
Why Yellow?
The colour isn’t actually pure yellow.
The official shade is often referred to as “optic yellow” and sits somewhere between yellow and green.
It was chosen because it provides exceptional contrast against a variety of backgrounds and remains highly visible under different lighting conditions.
The result is a ball that is easier for players, spectators and television audiences to track.
A Small Change That Changed the Sport
The colour of a tennis ball has no impact on how it bounces or performs.
Yet the move from white to yellow transformed how millions of people watch the game.
The next time you’re watching Wimbledon, the Australian Open or your local club championship, remember that one of tennis’s most iconic features exists largely because television audiences needed help seeing the ball—and because a future wildlife broadcaster thought sport could be shown better on screen.
