Amazing. It’s relatively easy to find color photos of this, for example one of the very last pics here, from 1970: https://www.esquire.com/sports/g36954688/wimbledon-1970s-pho...

But what is the oldest color photo of white ball tennis?

Also, do we have a good source for this story, because it’s not mentioned on Wikipedia: ”In 1972, the International Tennis Federation introduced yellow balls, as these were easier to see on television. Wimbledon continued using white balls until 1986.”

The only color photo of a ball in that link that I saw was #32 which is from 1978, which would support the idea that Wimbledon did not switch in 1972.

Oh yeah, you’re right, I just gave it a quick scan for balls and thought they were all from 1970.

What do you mean tennis balls are yellow? I always thought they were green? https://en.wikipedia.org/wiki/Tennis_ball#/media/File:Closeu...

They're officially yellow. Many people (~50% in my experience) perceive this colour as green though.
