ColorChecker

This is the familiar standard ColorChecker from X-Rite. It was designed to help get accurate color reproduction with film and has also proved itself very useful for digital photography. Consisting of 24 patches, it was designed to have reflectance spectra which mimic those encountered in common imaging situations. There are patches which represent skin colors, foliage, blue sky and other common colors; primary hue colors of red, green, blue, cyan, magenta and yellow; and a six step gray scale. The size is about 8 x 11.5 in. (approx. 20 x 29 cm.).
