### I really do not understand this paragraph at all. "Red/green signal
inverter" ? There isn't really a color signal extracted at the level of the
retina or optic nerve, the color information is extracted at higher levels
of the nervous system. Do you mean rewiring the retina so the L cones and
the M cones swap their connections somehow? I guess it would give you a
pretty psychedelic experience, possibly color blindness, until the higher
levels of the brain rewired themselves to respond to the altered input.

### Oh, not ignoring. Nobody knows why signal processing through these
differing parts of the neural network feels as it feels, rather than
feeling as something else. This is the hard problem of consciousness.
Nobody has even the rudiments of the knowledge of ontology that is
presumably needed to solve this problem.

Since the problem is way beyond my (or anybody else's) capabilities, I
defer further analysis until and if new pertinent information is available.
I would advise all people to do the same.
