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.

Acetate plastic base of Kodacolor lenticular film embedded in epoxide resin. The emulsion layer usually placed on the opposite side of the acetate base has been removed beforehand and is therefore not visible.

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 and the granular structure defined by the density of the silver is visible. In this shot the lenticules were showing towards the light source and the emulsion towards the camera. This enables an undistorted recording of the emulsion layer.

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.

Additive 3 color: Line screen and mosaic, still photography
“Another method of producing a line screen was patented in 1904 by the German Robert Krayn, and was demonstrated by him in November 1907. Krayn stained very thin celluloid sheets red, green and blue, and cemented them interleaved to form a thick ...

“Every element of a cross-lined screen acts as a pinhole camera, and reproduces an image of the aperture of the objective in whose rear focal plane it is placed. Thus, when using a square stop, the dots in the halftone produced will be square ...
