Rick Coates' aaarticle on color is very informative and I would like
to add just one note:

The cones of the eye are actually sensitive to three somewhat overlapping
frequency ranges, not three specific frequencies of light.  I believe
this may be why additive color "works".

That is, if our blue-sensitive and green-sensitive cones are excited to
some degree, our vision system interprets this as a color in between,
even though it could be a mixture of blue light and green light.

By the way, this article introduces a new term, "phenomenae," which I
take to be a plural of "phenomena."  However, "phenomena" is itself
the plural of "phenomenon," so this must make "phenomenae" a super-plural.
Wow!  What a concept!! :-)

(Please - no anti-spellingflame flames!  I'm just kidding!)
