The most authoritative work on the color instabilities of films and papers is:
Henry Gilmore Wilhelm The Permanence and Care of Color Photographs, Preservation Publishing Company, Grinell, Iowa, USA, 1993
The full 20 chapter volume is available for downloading in PDF format from the www.wihelm-research.com web site without charge.
This book is
essential reading for anyone who has to deal with older colour
pictures. Henry Wilhelm is hereby thanked for granting permission to
use the graphs in the first part of this help file and to quote from
his book.

Fabrizio Di Vittorio
of HiComponents, Ladispoli, Italy is hereby thanked for implementing
and adding a fast version of the ACE algorithm of Rizzi et al. and a
modified version of the Meylan-Süsstrunk method to the
HiComponents package at the author's request.
Rog Palmer of
