[net.graphics] Chromaticity Matrices

trainor@ucla-cs.UUCP (04/13/85)

Does anyone out there have references or algorithms for computing
the chromaticity matrix for a particular color monitor.  This is
used to compensate for differences in color hardware.  I am using
an Apollo DN660 color node in 24 bit imaging format.  If you've had
any good/bad experiences with this particular machine, I'd also like
to hear from you...

Check out the proceedings of Siggraph 1983 for a paper by
Bill Cowan (from NRC, Canada).  He presents an method for
finding the chromaticity tri-stimulus (sp?) values for monitors.
The procedure can be automated.

P.S. It's good reading for anyone who is interested in
accurately reproducing colours.
