The Color Transformation Language, or "CTL," is a portable and platform-independent scripting language and interpreter, is intended to be used as a building block for color management systems as well as for sharing transforms in a common format.

CTL addresses an industry need to precisely and unambiguously describe and share color transforms that are routinely used in motion picture mastering. For example, transformations between various color spaces and film density encodings can be defined in a CTL program that can be delivered along with image data, thus ensuring the image is properly rendered for display or other processing steps.
