Re: Colors

This is a very good question that philosophers have been asking, perhaps
since humans first appeared. However, it is well known that many people

yellow and blue etc.Consequently it stands to reason that the sensations
that people get
when viewing different colors varies from person to person.

Pathology aside, I'd expect that the differences would involve encoding
algorithms and neural processing... and possibly each infant brain must
create its own version. Perhaps a visual analogy of "perfect pitch"
exists (if indeed "perfect pitch" arises when a particular infant brain
discovers an improved algorithm.) Some of us end up with the better
stuff, while others make do with a solution which is merely good. If we
were purely genetic robots, then all eyes and brains might be identical.
