Coloureq.txt, a document containing equations relating to colour spaces
and colour transforms, available as ASCII text from;

  ftp.wmin.ac.uk

and, if you have a web browser, via;

  http://www.wmin.ac.uk/ITRG/extra.html

We recommend that this doc is read in conjunction with Charles Poynton's
documents, GammaFAQ.pdf and ColorFAQ.pdf for a more complete introduction
to colour systems. They are available from:

  ftp.inforamp.net/pub/users/poynton/doc/Colour/

in Acrobat PDF, PostScript and ASCII text formats. If you have a web
browser, consult Poynton's Gamma and Colour FAQ page;

  http://www.inforamp.net/~poynton/Poynton-colour.html

Good refs are berns et al, color research and application around nov 1993 - mail me if you need an exact ref.
