ABSTRACT:
A system and method for converting a color uses an extended color space to convert a color from a first color space to a second color space. The extended color space is extended from the second color space. In other words, the extended color space has increased valid component ranges compared with the second color space to accommodate the conversion of any valid colors from the first color space. Subsequent operations on the converted color in the extended color space occur without the presence of conversion artifacts found in many conventional color space converters.
