>> Would you say AM/FM radio waves exist only in our mind?

You're tweaking the analogy.

I didn't wrote 'electromagnetic waves exist only in our mind'. I wrote the qualia 'color' exists in the mind as the highly processed result of the activity of certain complicated structures in space-time. Some carriers of these structures, that is some humans that are convinced the idea of science is reasonable, like to call these structures brains. So a lot of people on this planet, but by far not all. Others call them 'soul' or whatever is the currently most useful and hardest to disprove in their environment.

The electromagnetic waves that trigger certain sensors in the eyes and trigger that processing are outside those brains. Or at least those brains assume they are. Assume with more or less good reason. But to complicate the thought, that is an assumption. That is, an element of the mind.

But anyone in their right mind should back away from the abyss of solipsism now, right?

>>Our eyes are sensitive enough to detect differences in the wavelengths So you are not seeing colors, but differences in wave lengths? That maybe, but most of us do see 'colors', that is a subjective perception? Do you see a red rose or a '620 to 750 nm' rose?

Sorry, but I just love to ask people, what is 'red'? Just describe it, can't be that hard.
