Please access detailed information on over 250 individual film color processes via the classification system on this page, display the Timeline of Historical Film Colors in chronological order, browse by image, search by color, search via the tag cloud at the end of this page or directly on the search page, or see the contributing archives’ collections on the header slides.
This database was created in 2012 and has been developed and curated by Barbara Flueckiger, professor at the Department of Film Studies, University of Zurich to provide comprehensive information about historical film color processes invented since the end of the 19th century including specific still photography color technologies that were their conceptual predecessors.
Timeline of Historical Film Colors was started with Barbara Flueckiger’s research at Harvard University in the framework of her project Film History Re-mastered, funded by Swiss National Science Foundation, 2011-2013.
In 2013 the University of Zurich and the Swiss National Science Foundation awarded additional funding for the elaboration of this web resource. 80 financial contributors sponsored the crowdfunding campaign Database of Historical Film Colors with more than USD 11.100 in 2012. In addition, the Institute for the Performing Arts and Film, Zurich University of the Arts provided a major contribution to the development of the database. Many further persons and institutions have supported the project, see acknowledgements.
Since February 2016 the database has been redeveloped in the framework of the research project Film Colors. Technologies, Cultures, Institutions funded by a grant from Swiss National Science Foundation. Since 2016, the team of the research project ERC Advanced Grant FilmColors has been collecting and adding written sources and photographs. All the members of the two research projects on film colors, both led by Barbara Flueckiger, have been capturing photographs of historical film prints since 2017.
Follow the links “Access detailed information ›” to access the currently available detail pages for individual processes. These pages contain an image gallery, a short description, a bibliography of original papers and secondary sources connected to extended quotes from these sources, downloads of seminal papers and links. We are updating these detail pages on a regular basis.
More than a decade of research on film colors, countless visits to archives to explore and document historical film colors for the Timeline has led the team to develop the scientifically proven multispectral scanning workflow Scan2Screen.
Based on an in-depth study of 8 leading commercial film scanners the team identified core requirements to capture historical film colors in a more comprehensive and future-proof way.
Since the earliest days of cinema, film has been a colorful medium and art form. More than 230 film color processes have been devised in the course of film history, often in close connection with photography. In this regard, both media institutionalized numerous techniques such as hand and stencil coloring as well as printing and halftone processes. Apart from these fundamental connections in terms of the technology of color processes, film and photography also share and exchange color attributions and aesthetics.
This publication highlights material aspects of color in photography and film, while also investigating the relationship of historical film colors and present-day photography. Works of contemporary photographers and artists who reflect on technological and culture-theoretical aspects of the material of color underline these relations. Thematic clusters focus on aesthetic and technological parallels, including fashion and identity, abstraction and experiment, politics, exoticism, and travel.
Color Mania contains a general introduction to color in film and photography (technique, materiality, aesthetics) as well as a series of short essays that take a closer look at specific aspects. An extensive image section illustrates the texts and color systems and continues the aesthetic experience of the various processes and objects in book form.

According to the image placement of the Super-8 motion picture standard the image is divided vertically into triplets of R, G and B filter lines. The emulsion layer has been removed before this image was taken.

Comparision of the linear filter structure of Polachrome 35mm instant slide film and Polavision Super-8 motion picture film. While the technical concept behind the two film stocks is the same, the Super-8 film was produced with linear filters of a smaller width. Based on the given width of an RGB filter triplet and the 135 still image size there are about 920 horizontal RGB-triplets per image for a Polachrome slide. The Super-8 film image is rotated by 90° compared to the 135 film still image and has about 340 vertical RGB-triplets per frame. The positioning of the image content compared to the filter lines is indicated in the picture.

"Polavision (top) vs. Kodachrome 40: These are blowups from closely matching frames of Debra Goldie, filmed simultaneously with a Polavision and a conventional super 8 camera, side by side, with the Twi Light quartz lamp mounted on top of the former. Subject distance was 6 ft., but the super 8 camera was focused for 10 ft. – same as the Polavision camera at its close-up setting. Both Polavision and Kodachrome 40 are closely equal in speed, but differ distinctly in structure, faithfulness of color rendition, and latitude, as is obvious from these frame reproductions. What can't be seen is the relative opacity of Polavision: according to our measurement, it transmits less than 9 percent as Kodachrome 40. However, the lab that made the duplicate transparency blow-ups of the frames found that it had to give a full six stops extra exposure."

"C'est devant un immense agrandissement de l'intérieur d'une cassette Polavision sur la-quelle se découpe la silhouette de l'orateur (ci-contre à gauche) que le Dr Land présenta son invention. Ce document permet de distinguer les poulies de guidage du film (1 et 2), la réserve de produit de traitement et son bec ré-partiteur (3), la bobine débitrice (4), l'ensemble formé par le presseur de film et le prisme (5), la poulie d'entraînement du film (6)."
"It was in front of a huge enlargement of the interior of a Polavision cassette on which the silhouette of the speaker was cut out (opposite left) that Dr Land presented his invention. This document makes it possible to distinguish the guide pulleys of the film (1 and 2), the supply of treatment product and its distribution nozzle (3), the supply reel (4), the assembly formed by the presser of film and the prism (5), the film drive pulley (6)."

The production of the Filter structure on Polavision film includes the use of a lenticular surface, which is removed after the process. The lenticules are not involved in recording the color information during the taking of images in the camera.

In the Polavision instant color film process the negative image recorded during the exposure of the film is neither developed from a latent image to a visible negative nor is it removed from the film. The latent negative stays as a layer in the film and is responsible for a slight attenuation of the image’s highlights.

Focal travelling through the 3-dimensional structure of Kodacolor lenticular film. In the beginning the linear lenticular structure is visible and towards the end the emulsion layer comes into focus. In this shot the lenticules were allocated towards the lens of the microscope and the light source at the side of the emulsion similar to the configuration in projection. As a consequence the graininess of the emulsion is not visible as with the film flipped to the other side. The structure is optically distorted perpendicular to the linear structure of the lenticules.
