# The Color Transformation Language #
|
|
|
|
The Color Transformation Language, or CTL, 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.
