This implies that color *could* (not *must*, *could*!!) be defined by an
external, objective standard, which would be potentially quantifiable on an
interval or ratio scale in intensity and purity. Some people, of course,
are missing certain types of cones. Also, in some animal species, there is
variation among individuals as to the protein sequence of some of the
photosensitive proteins in the cones, so that perception of say <blanu>
would be different for different individuals. I don't know if this is true
