Mauve in spectrum?

susanargus says:

This looks like a reason to "exclude" magenta (and mauve) from the
spectrum, and I'm not sure Robert Norton presented one to include it,
though he did say

>>Every color the eye can detect is in the solar spectrum.

On the other hand, susanargus and Robert seem to agree that folks don't
have magenta (or mauve) receptors, and perceiving it is a complex process.

Plus we've still got the big account found by Michael Workman at
http://www.ch.ic.ac.uk/motm/perkin.html of Perkin's coming up with the
first synthetic organic dye, mauve (if I understand "aniline" right). This
is pretty close to st.'s first nonnaturally occurring color, if not quite
GR's "'first new color on Earth.'"
