[Frameworks] 16mm prints turned pink

[Scott Dorsey]

Yes.  There is a warning on the box when you buy the film about color dyes
changing in time and film not being warranted.

Eastman prints both from reversal and negative tend to go red.  LPP prints
tend to go red much more slowly than SP prints.  Fuji print stocks tend to
go blue and get smoky blacks instead of going red.

Agfa print stocks with Eastman chemistry go red, Agfa print stocks with 
ball and chain dye coupler chemistry are sometimes very stable and sometimes
lose all color completely, depending on the pH of the wash water at the lab.
Kodachrome prints are very very dark-stable but fade faster with light.

Color film is not considered acceptable for archival storage.
