A list of early hand colored movies using no established technique. Pictures included where possible. Color movies first appeared as early as 1903. Today, most films use virtually the same processes for color. In the early days, however, various systems were used, including different film stocks, techniques, cameras, etc. The rules of cinematography and film development had yet to be written as no standards had yet been set. In 1935 the Technicolor 3 step process (Process 4) was introduced and the major studios set it as the standard. Since then, even more advanced color techniques have been invented.
