I haven't "solved" the problem of how the two squares can appear to have
different colors and yet be the same color, so I have no need of coding
techniques to hide my solution.

I would, however, appreciate an (uncoded) explanation as to how the
squares can appear so different in color to the eye and yet be the same
color from anyone who knows the answer or can figure it out.

Pattern recognition, like speech recognition is a difficult task for machines.
There are layers of post-processing built-in to the liveware senses that
have to be laboriously discovered or counterfeited for reasonable sensing:
processing of the kind we think is trivial.
