| Description |
English: The "primary" and "secondary" colors in a four-color print process. Specifically, these are the C, M, and Y inks of U.S. Web Coated (SWOP) v2 printers, and their mixtures at 100% strength. Because all three ink colors (as well as G, the 100% mixture of C and Y inks) are out of the sRGB gamut, the colors have been brought into gamut using the Relative Colorimetric intent of Adobe's CMM in Photoshop CS3.
Less technically: the "primary" CMY inks used by four-process printers are too intense to show on computer displays, so the colors in this file are only approximations. Note that the 100% combination of the three primary inks results in a muddy brown. This is one reason for the addition of black ink in the CMYK process. Also note that these CMY "primary" colors & their RGB "secondary" colors differ markedly from the RGB primaries and CMY secondaries of an additive RGB color model, such as is used by computer displays.
