If you replace glutamate with glycine then yes, the whole system would be
screaming that something was terribly wrong,  because glycine will have no
effect on glutamate receptors. Not only will any redness detection function
fail, but the whole brain will probably stop working and the subject will
die. That is why you have to do a more elaborate replacement: glutamate
with glycine, glutamate receptors with glycine receptors (simplistically -
you have to also make sure that the glycine receptors operate the same ion
channels etc. as the glutamate receptors). Once you do this, the whole
brain will work in the same way as before the substitution. It cannot
possibly say "wait, back up, that glycine isn't anything like its
neighbouring redness glutamate", because the neurons controlling speech
will all be firing in exactly the same way as before.
