CTL (Color Transformation Language) is a programming language for digital color management.
Digital color management requires translating digital images between different representations or color spaces. For example, the pixels in an image may encode the colors that should be seen when the image is displayed on a video monitor.
Printing this image on paper, or recording it on motion picture film requires transforming the pixels to an appropriate representation: Video, inks on paper and film all have different color gamuts and dynamic ranges. Color mixing is additive for video, but subtractive for inks and film.
Video and film typically use three color channels, while four or more inks are used for printing on paper. A color management system must transform each pixel in the original image to corresponding amounts of ink or film density values.
The Color Transformation Language, or CTL, is a small programming language that was designed to serve as a building block for digital color management systems. CTL allows users to describe color transforms in an unambiguous and concise way by expressing them as programs.
In order to apply a given transform to an image, the color management system instructs a CTL interpreter to load and run the CTL program that describes the transform. The original and the transformed image constitute the CTL program's input and output.
Color transforms can be shared by distributing CTL programs. Two parties with the same CTL program can apply the same transform to an image.
