I appreciate your patience, and persistence with helping me to better
understand.  I hear you saying that there is a bunch of different stuff
that has a redness property (i.e. lots of stuff reflects 700 nm light).
So, I can understand and agree with that.  The set of necessary and
sufficient stuff, which can result in a redness experience, may be diverse
(more than just glutamate).  But this set of stuff must be a seperate set,
from whatever has a grenness property, right?  In other words, you can't
replace something with a redness property with something that has a
greenness property and expect the person to say there has been no change?
So, in that way, what redness is like, is substrate dependent on that set
of stuff (all things that are redness), and you can't use something that
has a different colorness property, and expect them to say it is the same
redness?
