This doesn’t tell us what colour qualia is though. Reasonably and after seeing a paper [that I posted a while ago] stating that there is a ton of light in the brain, and that cells release photons, I can only imagine that those electrical signals are being converted to light. How else do we see colour?
The problem is that as you know, photons are merely a point of energy and physicists say they are transparent. Red is simply a stream of photons moving in that particular wavelength, - this doesn’t tell us what the quality of redness is.
When we observe what stuff is made of we loose sight of the holistic entity, what colour is, what water is, and what we are.
I divide it into what is existent [physical objects] and what is non existent [infinity, mind, qualities, etc]. if something is there in any way at all then it is in some way real, even a dream is a reality in that our minds are acting like computers and composing the images we see. Can we say that there is something which isn’t real? We can say something isn’t true or is an illusion, but an illusion is real graphics.
Indeed, and I do know all of that btw; the light is turned into electrical impulses which at the back of the eye is more akin to a kaleidoscopic image, and it then gets calibrated even before it moves to the optical cortex where the image is processed. So what I was saying above is that once the image has been processed we then see it, ergo the brain is making colour happen, which reasonably can only be done with light. But like what I am saying to james [above], there is an issue even with colour as a property of light ^^.
