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 code by Dan Bruton. This package provides an extended visible spectrum. However, it is possible to obtain the representation of the spectrum directly from the data of the »International Commission on Illumination« (CIE), and we have the choice between the data of (CIE 1931) and that of (CIE 1964}). Then we must choose a color space, sRGB, Adobe,etc.
