I'll be frank, I honestly do not understand where the philosophical dispute comes from. It seems incredibly silly to me.

The idea that a specific wavelength can trigger a specific electro-chemical response in a specific organ, which is then transmitted to a specific part of the brain which processes that response in a specific manner, but somehow the mental representation of such comes out of nowhere is nonsensical to me. Where would you even come up with such an idea?

Again I'm reminded of computer monitors. It's not magic by which they produce light of varying wavelengths and intensities on the screen, there is a real physical process going on. An electrical engineer could tell you all about in extensive detail.

Computers can distinguish between various colors very well, and can even process those colors without any light as input.

What do computers "see" when they see color?

Voted up, because you're absolutely right.
