Lesser Known Early Color Processes

Subtractive Color Systems

As is explained in more detail elsewhere on this site, there are two types of color motion pictures, Subtractive and Additive. These terms apply only to the method used to display the color image on a screen. Subtractive systems carry the color right on the film itself and Additive films use black and white records representing the color segments and separate color filters are used to add the color to the projected image. And I just used the word color four times in a single sentence. Subtractive color systems may use a limited two-color palette or the virtually complete three-color palette.

This list is by no means complete. It will be expanded as the data is unearthed.
