The ColorChecker Classic Target
ColorChecker Passport includes the legendary 24-patch X-Rite ColorChecker Classic. This target has been used by
photographers, videographers and for scientific evaluation of color rendition since 1976. In fact, it has become an
industry standard. Each of the 24 color patches represents the colors of natural objects, such as sky blue, flesh
tones and leaf green; and each patch reflects light just like its real world counterpart. Each square is individually
colored using a solid tone to produce pure, flat, rich color without dots or mixed tints.
The colors are produced by the Munsell Color Services lab, which has over 75 years of experience in the creation
of physical color targets and standards. They have produced color standards for use in a range of industries, from
sciences to commercial quality control tools. Each color is very closely monitored and controlled during the
manufacturing process, so you can be confident your color references are exact.
Here’s a closer look at the chart. Each of these patches can be used to get a quick visual check on color in your
images.
1: These patches represent skin tones.
2: These patches represent blue sky and foliage green.
