2-Strip and 3-Strip Technicolor Math: An Overview

2-Strip and 3-Strip Technicolor were early color motion picture processes developed in the 1920s and 1930s. The 2-Strip process used two strips of black-and-white film, one for the red and green components of the image and one for the blue component. The 3-Strip process used three strips of black-and-white film, one for each of the three primary colors (red, green, and blue).2-Strip and 3-Strip Technicolor were both subtractive color processes, meaning that they created color by filtering out unwanted colors from white light. The red and green components of the image were printed on the same strip of film in the 2-Strip process, and the blue component was printed on a separate strip. In the 3-Strip process, each of the three primary colors was printed on its own strip of film.2-Strip and 3-Strip Technicolor were both complex and expensive processes, but they produced some of the most beautiful and realistic color images of the early sound film era. 2-Strip Technicolor was used in a number of classic films, including “The Wizard of Oz” (1939) and “Gone with the Wind” (1939). 3-Strip Technicolor was used in a number of classic films, including “Snow White and the Seven Dwarfs” (1937) and “Fantasia” (1940).The development of 2-Strip and 3-Strip Technicolor was a major milestone in the history of color motion pictures. These processes made it possible to create realistic and vibrant color images that had never been seen before.
