Graphics Hot Spot |||| Mixing dominant colors red, green and blue, called "additive primary colors," in different combinations and varying intensities simulates a full range of colors of nature. Combining two, pure additive primary colors results in a perception of a subtractive primary color. To determine the limitations of the devices in a system, electronic color-management systems must define a color gamut, the range of color that can either be produced or detected by the devices. In our world, the entire range of colors available on a particular device is often referred to as "color space." If a color is said to be "out of gamut," it cannot be properly converted to a target device. A color monitor that displays a RGB signal has a greater color gamut than a printer, which uses CMYK. So, when an image is converted from a RGB model to a CMYK color model, the colors are shifted from one color space to the other in a process called "gamut mapping." 28 | Printwear PW_FEB13.indd 28 February 2013 1/18/13 10:02 AM
