ColorChecker

Common card · No. 437619

The ColorChecker Color Rendition Chart (often referred to by its original name, the Macbeth ColorChecker or simply Macbeth chart) is a color calibration target consisting of a cardboard-framed arrangement of 24 squares of painted samples. The ColorChecker was introduced in a 1976 paper by McCamy, Marcus, and Davidson in the Journal of Applied Photographic Engineering. The chart’s color patches have spectral reflectances intended to mimic those of natural objects such as human skin, foliage, and flowers, to have consistent color appearance under a variety of lighting conditions, especially as detected by typical color photographic film, and to be stable over time. In 2006, Gretag-Macbeth was acquired by X-Rite. In 2021, X-Rite spun off its consumer-level calibration products to a separate company Calibrite, which is currently producing the ColorChecker under the Calibrite brand name.
