The tennis ball is such an unassuming object in our lives that we take its appearance for granted. Who hasn' t stumbled upon one of them, forgotten, in the far corner of their closet or garage? Despite its passive presence, one of the most crazy internet debates of 2018 centered on its distinctive color: Is it actually yellow, or is it green? The shade in question originates from an unlikely source: David Attenborough, the legendary British documentarian known internationally for his Planet Earth series, played a central role in how we see the tennis ball today.
The sport of modern tennis was born out of the English game of lawn tennis, which by most accounts was invented in the 1870s. Lawn tennis was an outdoor adaptation of the indoor racket game " real tennis," which itself was an adoption of the French pastime jeu de paume, or " the palm game. " After many iterations (迭代), including balls made of cork, wool, and even human hair, the tennis ball found what was then its ideal form: a ball made of a rubber core encased in white or black melton, a tightly woven and felted fabric.
For nearly a century, tennis balls were white or black. It wasn' t until 1972 that tennis balls took on their bright neon colour. At the time, Attenborough was working as a studio controller for the BBC. In the late 1960s he had led the charge for the BBC to broadcast Wimbledon, perhaps the most iconic of tennis tournaments, in color for the first time ever.
Broadcasting tennis in color brought the matches to life, but it made tracking the ball on screen difficult—especially when it fell near the white courtlines. So the International Tennis Federation undertook a study that found that yellow tennis balls were easier for home viewers to see on their screens. An official 1972 ITF rule change required that all regulation balls have a uniform surface and be white or yellow in color. However, Wimbledon did not change the ball color to yellow until 1986.
In 1991, the Chicago Tribune ran a story about white tennis balls making a comeback. In reality, most manufacturers never stopped producing white balls in smaller quantities. Grant Golden, a former United States clay court champion, declared that the comeback of white tennis balls would " go right down the toilet" because " the yellow ball is perfect. "
The unmistakable shade of the tennis ball is officially called " optic yellow" by the ITF. The next time a tennis ball comes rolling out from the recesses of your closet, take a moment to regard the power of its humble design.
