### I don't know where you are getting this fixation on glutamate from. The
coding strategy has nothing to do with glutamate vs other
neurotransmitters. Red and green coding neurons are the same class of
neurons with the same neurotransmitters. The specificity of coding for
colors comes from their location within the neural net, or in other words
from their respective patterns of connections to other neurons. Also, the
color cortex is not the primary visual cortex, it's on an intermediate
level in the visual center hierarchy. Also, color is assigned only to a
very small fraction of inputs from the retina, specifically to the foveal
(central) part of the visual field.
