I think we are just talking past each other.
You said you only have redness if "ONLY THE RELEVANT OBSERVABLE BEHAVIOUR
of each component of the system is preserved".  Then only Glutamate
behavior is the relevant observable behavior.  And when one is aware that
it has changed to greenness, it is the different glycene behavior that is
the only diferent relevant observable behavior.  Isn't it?  Or can you
substitute half of the strawberry redness "relevant observable behavior"
with greenness "relevant observable behavior" and the system will still say
all of the strawberry is red?
