British color film company (est. 1908) using early additive color process — competed with Kinemacolor. Failed due to standardization issues and Technicolor competition.
The early days of British color film were a jungle of competing processes—and the Natural Color Kinematograph Company was right in the thick of it. Founded in 1908, the company pursued an additive color approach that worked with two primary colors: red and green were exposed alternately on the film and later superimposed during projection. The principle was elegant, but tricky in practice—any camera movement, any projection error led to color fringing and flickering.
What distinguished the process from Kinemacolor (its strongest competitor): Natural Color attempted to achieve more stable image quality by experimenting with finer filter combinations. On set, however, this meant significant additional costs—special cameras, strict exposure control, little room for the DoP. In post-production, it became even more delicate: every print had to be produced with extreme precision, otherwise the color effect was destroyed. For studios, this was a horror scenario—reproducibility was simply not guaranteed.
The crucial problem lay less in the technology itself than in standardization. By the end of the 1920s, there was no binding cinema laboratory that processed Natural Color according to the same parameters. Every light, every developing bath led to different results. Added to this: Technicolor—initially also additive, but then with the subtractive process—offered a significantly more robust alternative. The Technicolor three-strip light-color system was more complex in camera technology, but it was stable and reproducible.
By the late 1920s, Natural Color was practically finished. The company could not keep up with Technicolor's systematic approach to standardization and control. In archives, one can still find some films with Natural Color material—the colors often appear strangely muted, reddish, as if the green has collapsed. This is typical of the additive process under suboptimal storage conditions. Today, these films are a lesson that color technology without industrial standardization is doomed to failure—no matter how elegant the theory looks.
