What shade are tennis balls?
All of them have one other widespread attribute: they share a shade, known as optical yellow, which in 1972 was adopted by the ITF – therefore the ‘age’ of the present ball. Earlier than that, the balls had been white or black relying on the taking part in floor. White balls are nonetheless manufactured. There are additionally purple, orange and inexperienced balls – designed for freshmen. There are additionally custom-made balls in pink, purple, black or totally different shades of blue. However in all official senior tournaments the ball is yellow.
The change in shade occurred because of the calls for of tv transmissions. In 1972 tv was already in shade everywhere in the world (though in Spain it was not generalized till 5 or 6 years later). On the finish of the Nineteen Sixties, the particular person in control of the BBC broadcasts (which, in fact, was in control of Wimbledon) was the famend documentary filmmaker David Attenborough.

White continued for use for a couple of extra years in some competitions, such because the Davis Cup or the outdated Wimbledon, which resisted the change till 1986, because it didn’t maintain its finals on Sundays till the tv networks compensated it adequately.
Thus, till the Nineteen Seventies and for nearly a century, tennis balls had been white or black. At this time they’re yellow, though some recalcitrant nonetheless converse of ‘inexperienced’.
