Abstract: There are many digital color devices: monitors, printers, film and video recorders. The goal of device independent color reproduction is to provide a single, standard representation of color that can be rendered on different media to produce the same visual result. Such representation must go beyond the CIE standards to include information about inter-color relationships and media appearance. The goal of these notes is to provide an overview of current practice in this area, plus information on colorimetry, additive and subtractive color systems, and color reproduction practice, all as applied to the problem of device independent color.

Color reproduction is then the process of transforming from the input colors to the output colors. In a device independent color reproduction system, the input and output transformations are defined relative to a standard represen- tation for the color. This standard representation is usually based on some form of color measurelnen t defined by CIE standard colorimetry. The goal in color reproduction is to duplicate the appearance of the original on the target media. Colo
