Are tennis balls green or yellow? That is a question that has caused quite the stir on social media over the past 24 hours but we finally have an official answer thanks to tennis legend Roger Federer.
It all started with this poll:
Okay Twitter… help me out here. I have a bet on this…
What colour are tennis balls????

The poll seems to suggest most people think tennis balls are green (you weirdos, they are definitely yellow), but what does an expert think on the topic?
If anyone could settle the debate, it was Federer.
So let’s check in with him:

There you have it. Case closed.
And in case you want to get really specific, tennis balls are fluorescent yellow or “optic yellow.”
Yellow and white are the only colors approved by the ITF, and most balls produced are a fluorescent yellow known as “optic yellow“, first introduced in 1972 following research demonstrating they were more visible on television. Tennis balls are filled with air and are surfaced by a uniform felt-covered rubber compound.
