Well, would it exist if you were blind? YES

This sounds like the question: If a tree falls in the forest and there is’nt anyone around to hear it, does it still make a noise?

It would make a sound (the physical waves transmitted through the air) but not a noise (the human perception of those waves.)

Does it exist for you? Does color exist or radiation are they really one in the same? Maybe the radiation would be there but not color?

If the Earth was completely wiped out of life, it could still be possible that there could be some type of mechanism that could interpret colour from the stimuli.

What is “hue”? How would you know if they interpret hue instead of color? More importantly how would they know??

It could exist whether or not an intelligent being could distinguish what it is. It is entirely possible that other organisms to be able to sense something in a way we cannot perceive. That does exist, even if we have yet to discover it, much less even having the ability to do so.

I would assume the real sticking point is going to be the definition of color. If you tie it to the actual ability to perceive it, then it could only exist if that ability was someway present in the universe. If you tie it to the phenomenon that produces the stimulus then it could exist regardless of it being able to be perceived or not. A thing can exist whether or not it has been discovered, well on second thought that is on condition that the universe is more than just an ‘illusion’ in my or your mind. I myself have no problem tying it to the phenomenon.

I know that to some this qeustion may seem a bit bogus, but…

Is colour an Intrinsic part of are reality? For example, if there were no colours, not even black or white, would the universe still exist? Can a universe exist with out colour?

It’s part of the universe for us - AFAICS, it is no more real or unreal than the physical entities (photons, & so on) through which we perceive it.​

ISTM that all these phenomena are modifications of creation in different ways, according to the manner of the creature that is in the environment in which the modification is apprehended. So we apprehend colour in a way proper to our being human - and a cat does so in a way proper to its being a cat.

The ultimate reality is not the physics or the chemistry, but the God in relation to Whom all physical (& all other) phenomena are contingent creatures: whether they are neutrons or the angelic orders. I think we have to go back “beyond” the universe, as it is itself not ultimate - it is dependent for all its being & in every respect on its Creator 🙂

I think Pete has hit the nail on the head for me. “Sounds” are a matter of “perception” not actuality. The answer is, if nobody was around to hear it, there would be no sound; the only thing that would be there is the vibrations of air that we perceive through a union of the brain and how it reconstructs the data of those vibrations that we perceive as sound.

It makes me wonder if we really perceive reality how it really is in the real world.

Some people have said that quantum physics suggests that there has to be “viewers” in order for some things to exist?
