Was that dress blue or gold? How about that old Vans shoe⌠turquoise and grey or pink and white?
And now, the latest great debate of our timeâŚ
Are tennis balls green or yellow?
This time, however, itâs Roger Federerâs fault.
During a visit to Chicago to prepare for Septemberâs Laver Cup, the worldâs top-ranked tennis player was asked the divisive question by a fan.
In a video captured by the fanâs daughter, the man can be heard shouting âHey Roger! Are tennis balls green or yellow?â
The tennis great flashes a big grin before responding with âTheyâre yellow, right?â

Why would you play on green grass with a green ball? Of course itâs yellow

Iâve always thought tennis balls were green but if says they are yellow who am I to argue with the GOAT. They are yellow

Whatever Roger says!

Other users provided more specifics for their choice of colour.
I believe the color is listed as âchartreuseâ or âyellow greenâ on color charts, so it might qualify as both but def not just yellow.

Mystery solved
If you have ever seen a tennis ball it's clearly yellow...
Finally, there were some who just couldnât decide.
