Right, much of our problems are just communication issues, I think.

I challenge you to find (I've been searching for some time) any peer
reviewed journal article on perception, which uses more than one word for
all things "red". I haven't managed to find one, yet.

When we look out at the world, we see a very colorful world. But as we've
been talking about, none of those colors are properties of the world out
there. And my redness could be like your greeness, so whos red? Those
colors are a property of something, maybe some kind of process as you say,
in our brain. But nobody can tell us which of all our descriptions of
stuff in the brain, is a description of redness. As it indicates in both
of the images in "Representational Qualia Theory
everything out side of the head is in black and white. This is because all
objective information is abstract, devoid of any color information. The
only thing of any color, is the color of our knowledge of the world.

Redness must be a quality of some set of physics. We think it is a quality
of the strawberry, but it's not. It's a quality of our knowledge of the
strawberry. Of all our objective descriptions of stuff in the brain, one
of those is a description of redness.
> I can experience redness, but there is no such 'thing' as redness.
I would disagree with this. There must be something physical (even if some
kind of process) which is what we directly experience as a single pixel of
redness. And all of our pixels of colorness must be able to be
computationally bound together into a composite qualitative experience of a
strawberry, and such. Certainly you would agree that you could objectively
observe, and fully describe, whatever this "process" is, and be able to
objectively describe a change to this process, which we experienced as

This sounds like the popular consensus, that redness "arises" from some
process. The problem is, I bet you can't give any actual objective
falsifiable description of what kind of process would have a redness qulia,
for a single pixel, and how this process, for this single pixel would
change, when it changed to greenness.
I think this is where we differ most. You think that 'redness' is a thing
> that has an existence independent of a mind. Am I right?
Objective descriptions of stuff in the brain provide no information about
the color they are describing. Al I"m saying is one of those descriptions,
even if it is some kind of process, that is what we directly experience as
redness. If you could provide a description of a kind of process, from
which a redness quality would arize, I'd be happy to substitute that for
'glutamate' as an easily falsifiable candidate for what we directly
experience as redness.
