Mondo Knows Facts
Colour negatives faded within decades
Early colour film stocks lost their dyes, leaving pink prints Many films shot on Eastmancolor and similar stocks in the 1950s to 1970s have faded badly because the cyan dye layer breaks down faster than the others, leaving a magenta or pink cast. Preservationists now store colour negatives cold and make separation masters, black-and-white copies of each colour record, that survive fading. It sits in Mondo's movies & tv collection, one of 200 facts that each trace back to the reference below.
