The article presents definitions for the terms color space and color system. In agreement with David Brainard (2003), it classifies the color systems in two groups: color appearance and color difference. Amongst the existing color systems, the article also presents the description of the Munsell Color System, one of the most used among the color appearance systems, and of the CIE 1931, one of the most used color difference systems. In addition, an historical retrospect of the search for color spaces that represent the human color perception as well as the reconstruction of color spaces with electrophysiological and psychophysical methods, are described. Many of these reconstructions use the multidimensional scaling methods (mds). Finally, the article presents the possibility for reconstruction of color spaces of patients with acquired dyschromatopsia as a distortion of the color space of normal trichromats.
