Green is a construct of the eye and brain.

I'm not sure I buy that. Your eye and brain may be fooled into perceiving "green" in some instances, but that sounds more like an instance of "aliasing," which is a well-known phenomenon in signal processing.

We could test your statement, and the control would be to see whether people with "normal" vision (however defined) would ever identify your "Platonic Green" as some other color. Dollars to donuts they won't.

Not a useful test. People can identify cows, but there is no Platonic cow.
