[AMIA-L] early color system

[Elif Rongen <erongen@FILMMUSEUM.NL>]

Dear AMIA-members,
we have a question about an early full frame color system.
We hold a film that looks like a demo for a "new" color system. The
stock looks like a combination of b/w positives that were tinted
alternately in red, green and blue dyes.
The French intertitles invite the audience to experience the colors, and
to compare the images to their b/w originals.
Unfortunately we miss the beginning which might contain more info.
The system looks like the Herault Trichrome Process as described in
"Colour cinematographhy" by Major Adrian Bernard Klein, 1939.
However if we project the film at 24 frames p.s. as explained in the
book, the colors don't work. It is clear that the projection must be
speeded up, in order for the colors to blend and work well.
The stock edgemarks are various; Kodak and Pathe Cinema France, between
1924-1927.
The images seem to come from various films, fiction and non-fiction.
Nature documentaries, and probably Pathe fashion newsreels, used in
order to illustrate the color system.
Could anyone help us establish which system this is, or has anyone come
across similar material?
