The ColorChecker Classic target is an array of 24 scientifically formulated colors that has been the leading industry color reference target for more than 40 years. It is designed to deliver true-to-life color reproduction so that photographers and filmmakers can predict and control how color will look under any illumination. Each of the 24 colors found on a ColorChecker target represents the actual color of natural objects, such as human skin tone, foliage and blue sky, and reflects light just like its real-world counterpart. Since these colors exemplify the color of their counterparts in the natural world and reflect light the same way in all parts of the visible spectrum, the squares will match the colors of representative samples of natural objects under any illumination, and with any color reproduction process. Each solid patch is formulated individually to produce a pure, flat, rich color.ColorChecker targets have been used by color perfectionists for the past decade to create custom DNG profiles orICC camera profiles when you combine ColorChecker targets with Calibrite ColorChecker Camera Calibration software.
