From what I understand, humans can see red green and blue and everything in the middle. Some animals I’ve heard see more colors than us, so what’s to say that some things in nature are colors that we don’t see? Who’s to say that some apples are red? And instead a different color that we don’t have a name for because we can’t process it?
How can we tell if this “apple” is as a matter of fact “red”.

Apples are red because they “reflect” that part of the spectrum that we can see, and object could reflect red and also part of the ultraviolet for example but since we can only perceive red we still say that object is red. We can use a thermal camera to “see” infrared but we don’t say it’s a different color because we can’t perceive it with the naked eye. In short colours are just the names we give to the parts of the electromagnetic spectrum that our eyes can perceive.
