Another reason that the old Technicolor color-separation masters have 
exhibited such great longevity is that the master strips are not in 
color at all, but rather are black-and-white film stocks merely 
*representing* the tonal variation of each of the three colors.

The point here is that well-processed black-and-white negatives have their
images in the form of metallic silver, which yields a much more stable image
over time than a color film stock, whose image is made up of three layers
of organic dyes.

This, of course, is a factor only when you're looking at a release print that
has recently been remade from the color-separation masters.

Somewhere (on this net perhaps?) I heard that a previously unknown set of
separation masters were found to an old movie (seems like it was GWTW),
enabling distributors to get a very fresh looking color print.
