Each of these devices reproduces a different range of colors, called a color gamut. As you move an image from your scanner to your monitor, and finally to a printer, the image colors shift. This shift occurs because every device has a different color gamut and thus reproduces the colors differently. RGB CMYK A B Photoshop Elements C The color gamuts of different devices and documents A.

Devices Color management translates the image colors so that each device can reproduce them in the same way and the colors you see on your monitor will be close to the colors in your printed image. All colors may not match exactly because the printer may not reproduce the same range of colors as the monitor.
