László Moholy-Nagy
An update to other post about color (e.g.) An interesting process of additiv color mixing is the socalled Dufaycolor process, which was e.g. used by Bauhaus Professor László Moholy-Nagy (see below Dufay Color photograph). A very recommendable book about his photographic works is the book:
Colour in Transparency – Photographic Experiments in Color, Fotographische Experimente in Farbe 1934-1946, edited by Jeannine Fiedler and Hattula Moholy-Nagy for the Bauhaus Archiv in Berlin, Steidl Publishers Göttingen
Some low-res examples from the book for the purpose of suggesting to buy the book:

Assembly (Vivex) process (a subtractive color mixing process), Study with pins and ribbons
