Does the color “red” exist?

Do not rush to answer.

Yes, we see it.

But most of the animals do not.

And not to mention that there are people who cannot see colour either.

Does the majority determine which things “exist” ?

Someone with whom I was discussing on the matter said: “Even if one person sees it, then it exists”. How true.

A simple statement with very weird consequences: If a “crazy” person sees a giraffe where everyone else is “seeing” a chair, does that mean that the giraffe exists? Do “crazy” people exist after all?
