Alas all of this is true. A Canyon Cinema I found most of the color prints
made in the 70's had turned red. This even happens when the film is never
projected. When I worked at the Encyclopedia Britannica in the early 70's
most of their prints had turned red. I am inspecting the 16mm film
collection at the SF ARt Institute and am finding the same situation with
some prints made during the 70's and some 1980 print.
