Summary description: Output of a color spectrum for different color models

Announcement text: ----------------------------------------------------------------------

To represent the spectrum of light decomposition, we have several
packages at our disposal with PSTricks: pst-spectra, xcolor, and
pstricks-add. All use the same source-acode by Dan Bruton.
This package provides an extended visible spectrum.-aHowever, it
is possible to obtain the representation of the spectrum-adirectly
from the data of the -+International Commission on Illumination-2
(CIE),-aand we have the choice between the data of (CIE 1931)
and that of-a(CIE 1964}).
Then we must choose a color space, sRGB,-aAdobe,etc.-a
