Cinecolor
This two strip color, was very popular with cartoons
(Comicolors). Magma color was actually Cinecolor. This was not a
full color process, though it could look quite nice. Unlike two
strip Technicolor, both sides of the film have emulsion layered
on top. It scratches very easily. In addition to Cartoons, many
features that were three strip tech in 35mm were made as
cinecolor in 16mm. Becky Sharp, A Star is Born, Nothing Sacred
were all printed in Cinecolor on 16mm. Becky Sharp has never been
made available in full color 16mm. A Start is Born was put into
general release in full color (Eastman) starting in the mid
1970's. To date only two 16mm prints of Nothing Sacred have been
made in full color (print downs from the Selznick CRI neg),
though the Yellow matrix has shrunk a bit in one scene, causing
what appears to be a registration problem.
