I think that they are yellow because if they were green then they would have to bee much darker then they are now.

Yay first to answer! A tennis ball is actually A yellowish green.

I think it's close but they are a kind of neony yellow to me.

How are they green? It could just be from the lighting or background that it’s in, obviously I think it’s yellow and I don’t know why it’s been brought up now because it’s always been yellow.

I'd think that the tennis balls would be yellow, a light yellow. I mean, they look lime, but I still think they're Yellow.

I always thought tennis balls were highlighter yellow,but this certainly made me think.

I am the first to comment !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
yay

There're flourescent green

They are obviously neon yellow!

I am the first one to comment!!

FIRST TO COMMENT!!!!! ??????????????

shall we say yellowishy green

It’s green very bright neon green

Well, I am up for a maybe. It could be a mix of green and yellow?? I wasn't really sure though. I am sticking up for my opinion. It might be a new colour, a bit of yellow and green? It is possible, isn't it?? :/

I think that a tennis ball is lime-green so I didn't vote. I hope Andy Murray agrees with me!

I think that a tennis ball is a really light green, but not quite yellow.

I think we should leave it yellow because the tennis playing grounds are green so they might find it a bit hard to see it . and the person who collects the ball will take longer

tennis balls are yellow and green. some brands can make them more yellow and others more green.

I play tennis but I'm not quite sure about the colour of the ball...

#firstcomment

I personally think they are neon yellow so I went for yellow

#FIRST2COMMENT!!!
Sorry about that. I vote yellow. Still funny, though. L.O.L.

Excuse me, computer. There is not 0 comments. It is perfectly clear that there is my comment that I just commented.
Seriously. Is technology REALLY smart enough to take over. Tut tut.

?

Aren't they different colours depending on who makes them? Some are yellow, some are green. Most of the ones at my school are green, but they have yellow ones too.

I think ? they are yellow because I would always say something like grab the yellow tennis ? ball.

I think a tennis ball is yellow tint because green is a little darker

I'm really not sure, it looks like it could be a mixture of both colours. Maybe some people just see it differently to others.

They’re obviously yellow because if they were green, and the tennis players were on a green court, if the ball got dropped, no one would be able to find it.

Tennis balls are definitely GREEN in my opinion, just really bright and a kind of lime colour.

Does it really matter? I think it was a very light green but I'm not really fussed whether it is or not

REALLY!!!
A GREEN TENNIS BALL!!!!!
Have you ever seen a green tennis ball?
You would never find a green ball if it got lost in grass

In my mind it’s yellow, but other people might think it’s green. It is like an optical illusion

:)

It is so green. It may be light but it is definitely NOT yellow. In my opinion, it is more of a neon green but not yellow.

I have researched and they are........................................YELLOW, well, a flurecerant yellow really. But they do look a bit green and all my family agree that they are yellow with a tinge of green, I'm not saying anyone is wrong though!

Yellow

I think they are a neon yellow which is basically a yellow with the characteristics of green

A tennis ball is like kind of yellowy green!!!!?????????

I think it could be both, it just depends on how you see it.

a tennis ballis a lime green

In pictures they sort of look yellow but they are definitely green!!!!

In my opinion, they’re mostly yellow, although I understand why some people say they’re green. They’re not completely green. It’s like The Dress all over again.

Well you can get green tennis balls and the green looks different to the yellow and that is a yellow tennis ball

grrrreeeeeennnnnn

I think a tennis ball colour can vary it can be yellow or green the only thing that matter is if it has the properties of a tennis ball and to be honest we shouldn’t be debating its colour but about properties.

yellow. Just yellow.

duh i was the first to comment :)

Tennis balls are more neon yellow than neon green, so I voted yellow.

I agree with izzie99!!!!??????????????

Neon Lime

Look at one, they're yellow.

I think they are yellow, but I have found a description of what they are like on google.

Tennis ball
Sports equipment
A tennis ball is a ball designed for the sport of tennis. Tennis balls are fluorescent yellow at major sporting events, but in recreational play can be virtually any color. Wikipedia

I think that they are neon Green

Definitely yellow!!

I think a tennis ball is green because my dogs ones are green but then the ones you use for tennis are sort of yellow so I don't know.

A LIGHT SHADE OF YELLOW

they are sort of a very very light neon green

I believe it (the tennis ball) is a very,very green shade
Still,I believe it has a bit of yellow

They look like a neon yellow not a green

If you look ? close its yellow

I mean there yellow!
I suppose it depends on the tennis ball as I have a red one but surly the normal ones are yellow!

How does everyone not see it's green!!!!!!!!!!!!!!!!!

?look it is 100% yellow

It's really hard to tell . but me personally I would say it is yellow , because if you bought a green one it would look much more darker. But other people may disagree with me so that fine.

I've never really thought about that before but now that I am I think It is just a very bright shade of green

NEON YELLOW

Soooooooooooooo yellow

I mean, sure the color could look green, but it is just neon! I totally agree w 'rivalgamer'. For a tennis ball to be green it would have to be quite a lot darker. (;

It's yellow obviously. Why would it be green?

Believe ME

They are just about green. The reason why they appear yellow is due to the fact that they are extremely fluorescent.

it's neon yellow... i asked my teacher!

ITS YELLOW!!!!!

it's green

Light green?

This is confusing I’m not sure

I THINK YOU ARE ALL WRONG! IT IS GREY! I AM COLOUR DEAF SO I CANT SEE COLOURS AND PRINGLES COST TOO MUCH NOWADAYS AND PIZZA ROLLS ARE BAD FOR THE WORLD!

It's obvious. I worked as a ballkid at the Australian Open a couple of times and I was holding them for hours. Even Roger Federer agrees...

more yellow than green

I think that a tennis ball is a lime colour. However, it is more on the yellow side if you ask me.

I think it is very bright yellow. I also have an argument for this as it is to help the the players see the ball better.

I think that some tennis balls are green, and some tennis balls are yellow. I think that this one is yellow though, but the ones i have at home are green. Maybe it's just the printer ink? I vote yellow for the now

Do you know those pictures on the internet that some people see one colour and other people see another? I think that tennis balls are one of those.

a tennis ball looks yellow but it is actually a really light florescent green

florescent-the colour of highlighters

The full balls that good people use are yellow, but you get green and yellow, orange and yellow and red and yellow balls.

I would call them greeny-yellow but they are more yellow than green.

Green definitely. Look at it closely , and it is green

GREEN ??????????????

I think that tennis balls are like a hi-vis jacket sort of yellow.

They are kind of like a neon green that turns yellow when its dirty

i think it is yellow!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1

a tennis ball is a very bright yellow.

I would say a mix of green and yellow

YEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEELLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOWWWWWWWWWWWWWWWWWWWWWW!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!(maybe green)

rrrreeeedddd yyyooo

To be honest, neither! They are between a neon yellow and a neon green depending on the brand.

I DUNNO!!! Highlighter yellow and neon green at the same time! AGH!!!!!

I say RED! (I have actually seen red tennis balls before tho). :O

Obviously yellow

greeeeen

tennis balls are neon they are not green nor yellow

though I think it is mostly greenish
