 The Sonochrome line featured films tinted in seventeen different colors including Peachblow, Inferno, Candle Flame, Sunshine, Purple Haze, Firelight, Azure, Nocturne, Verdante, Aquagreen, Caprice, Fleur de Lis, Rose Doree, and the neutral-density Argent, which kept the screen from becoming excessively bright when switching to a black-and-white scene.Tinting and toning continued to be used well into the sound era.In the 1930s and 1940s, some western films were processed in a sepia-toning solution to evoke the feeling of old photographs of the day.
