Class, am I wrong here.  Don't each of us see the "color" of objects
differently?  EG some see the snow as bluish and others as "white".  I for
example see purple as reddish and most others as bluish.  This is a problem
that artists face in every painting.  At least this is what I have been
told by eye guys.  But hell's bells what do they know.

BTW red/green color blind people perceive both colors the way most do grey
-- although I don't know how anyone could tell.

At the extreme I don't know that others don't see the sky as the same color
as I do green or yellow -- and they see trees as I do the sky or maybe
marigolds.  I wonder if it is possible to measure this.  Can someone please
comment on this point.
