A system for processing color information is based on carrying with color data, an indicator of the color space in which the data is represented. In this manner, the system is enabled to process color data from a variety of sources independent of the color space of the sources, because it is able to respond to the color space of a particular color value perform the necessary transformations to operate within any other arbitrary color and color space combination. The system provides for manipulating or combining colors independent of the source and destination color spaces. Also, the system operates on a per color component basis in user selected working color space, independent of the color space of the input or destination devices.

[ What is claimed is:] [1.] A method for processing color information in a computer system, comprising:specifying in a first memory location a source color in a color data structure; the color data structure including a colorspace field, a colorset field, a colorprofile field and a color data field, the color data structure being arranged to store color data associated with a source color space which may be one of a variety of color spaces including algorithmic and indexed color spaces, wherein the colorspace field contains an indication of the source color space if the source color space is an algorithmic color space, the colorset field contains an indication of possible indexed colors if the source color space is an indexed color space, and the colorprofile field can contain a characterization of the color space; the color data structure including a source color space parameter set identifying the source color space and source color data indicating components in the source color space, the source color space being user selected from a set of color spaces;specifying in a second memory location a destination color in a data structure including a destination color space parameter set identifying a destination color space, the destination color space being user selected from the set of color spaces; andcomputing with a processor coupled to the first and second memory locations a resultant color data structure in response to the source color data, the source color space parameter set and the destination color space parameter set, the resultant color data structure including resultant color data indicating components in the destination color space.
