Computer systems thatprocluce color images, usually consist ofcombinations ofhardware and software components that perform
different functions, such as capturing, synthesizing or editing images, incorporating images into documents, proofing, and
rendering results. Images, and the documents containing them, must be stored temporarily or archivally, and transmitted from
component to component. Users will be able to operate such systems more conveniently and flexibility if the parts communicate
with each other using a standard interchange format, allowing any conforming module to communicate with any other.
This paper discusses the requirements for such an interchange color space, comparing them to some ofthe criteria used to measure
traditional color spaces. Any computer interchange space should employ the principles of colorimetry to provide deviceindependence,
which is necessary if negotiation between components is to be avoided. Other requirements are accuracy and
computational efficiency of transforms to and from device-dependent and internationally standard spaces, ability to represent all
visible colors, maximizing the amount of space occupied by the most likely image color gamuts, and robustness against
quantization and roundoff errors. This paper proposes ways to measure the performance of color spaces against the defined
requirements and applies the tests to several well-known color spaces.
