One could quite easily argue the other side of the color disagreement=
-- that it is the scientists who have the definition wrong. =20
As Devil's Advocate, let me argue that color is the perception of the=
interaction of light with three widely overlapping broadband photose=
nsors. Stimulating the eye with a) a single frequency near the overl=
ap of two sensors b) two separate frequencies near the peak responses=
of the two sensors, or c) a broad range within the response regions =
of the two sensors will all create roughly the same response in the e=
ye. All three of these are "the same color". =20
That's why three colors (not four or five or two) are "primary". By =
choosing three inks or three lights that each stimulate primarily one=
receptor, then a rather accurate recreation of any color perception =
can be produced.

It's us physicists who messed it up by trying to equate a specific co=
lor with a specific wavelength ;-)
