In color-related fields, a color chart is a physical arrangement of standardized color samples, used for color comparisons and measurements such as in checking the color reproduction of an imaging system. Color charts are used to calibrate and to profile graphic devices, such as digital cameras and scanners. Therefore standardized IT8 targets are made by several companies including Coloraid.de, FujiFilm, Kodak, LaserSoft Imaging.[1]
Color charts can also be used to asses light quality, as in the color rendering index, where reflectance from a set of Munsell samples are evaluated.
The Munsell ColorChecker—first produced as the Macbeth ColorChecker in 1976 and still widely known as the Gretag Macbeth ColorChecker—a cardboard-framed arrangement of twenty-four squares of painted samples based on Munsell colors. Its maker Munsell Labs and parent Gretag Macbeth were acquired in 2006 by X-Rite, a color management and colorimetry company.
