Back in 1480, Louis XI of France made use of his crown by forbidding the filling of tennis balls with chalk, dirt, sand or sawdust and they should be made of good leather and well filled with wool. Others of the time were made of animal furs, animal intestines, human hair and many other odd substances, but the standards were being set way back for Kings Tennis or as it is called today, "Real Tennis". Lawn tennis was introduced in the 1870's where the court size was standardized, lawns in place and a vulcanized rubber ball was used.
Eventually control of the standards for tennis were removed from the French Crown and are now governed by the International Tennis Federation (ITF). There appears to be more regulations for tennis balls than for importing Panda Bears (that's another story for another day).
Anyway, what this is really all about is the color of tennis balls. For my childhood, the balls were a white cream color when new and came four to a sleeve. They eventually became pressurized and in metal cans with a pop-lid of only three. In 1972 the color of "Optic Yellow" was introduced. Why? The tennis ball received it major make-over for the sole purpose of making the balls more visible on TV!
About two years ago we started seeing this color on items other than tennis balls. First it was construction safety vests, then shirts, joggers apparel, police clothing, bike riders, bathing suits and now ladies underwear. Why ladies undergarments? I have no idea. I was doing some research but could not come up with an actual person responsible for the tennis ball color change but I am curious, is that individual responsible for the return of this color for other uses?
