In the 120 year history of film, several hundred colour processes have been developed. Many had their roots in nineteenth century still photography. This website describes all significant colour processes, but also puts them in a contemporary and historical context. The information on the website gives the technical detail on how the process works, but also describes how the process was received by the photographic and film communities of the time. There is also information on aesthetic or narrative uses, at the time of development and subsequently.
Timeline of Historical Film Colors
This is an information-rich site with a wealth of detail, wonderful and engaging examples and full references to further information. It is a work of scholarship and obviously also a labour of love.
An article describing the creation of the database is in the online cinema journal ‘Frames’: http://framescinemajournal.com/article/analysis-of-film-colors-in-a-digital-humanities-perspective/
