color depth The possible range of colors that can be used in an image. There are generally three choices with digital images: grayscale, 8-bit, and 16-bit. Higher color depths provide a wider range of colors but require more storage space. See also bit depth, color channels, grayscale. color interpolation The process of calculating additional color values from light captured via the red, green, and blue elements on the digital image sensor. color management system (CMS) An application that controls and interprets the reproduction of color between devices and imaging software for accuracy. See also ColorSync. color matching method (CMM) A software algorithm designed to translate color information from one device profile to another, such as from your display to your printer. ColorSync is a thoroughly integrated CMM used by Mac OS X. See also ColorSync. Color Monochrome adjustment An adjustment in Aperture that desaturates the image and applies a color tint of your choosing to the midtones. See also adjustment, desaturate, image, midtones, monochrome, Tint adjustment. color space A mathematical model used to describe part of the visible spectrum. Color from one device is mapped from the device-dependent value to a device-independent value in a color space. Once in an independent space, the color can be mapped to another device-dependent space. See also device dependent, device independent. colorimeter An instrument capable of measuring the color value of a sample, using color filters. A colorimeter is used to determine if two colors are the same. However, it does not take into account the light under which a sample is measured. Colorimeters are often used to calibrate displays and printers. See also calibration. colorimetry The science of measuring color both objectively and perceptively. ColorSync A color management system that is part of the Mac operating system. In Mac OS X, ColorSync is thoroughly integrated with the entire operating system and is available to all native Mac OS X applications. See also color management system (CMS), color matching method (CMM), ColorSync Utility. ColorSync Utility A centralized application for setting preferences, viewing installed profiles, assigning profiles to devices, and repairing profiles that do not conform to the current ICC specification. See also ColorSync, International Color Consortium (ICC), profile. color temperature Describes the color quality of light. Color temperature is measured in units called kelvins (K). See also kelvin (K), White Balance adjustment. Commission Internationale de l'Eclairage (CIE) An organization established in 1931 to create standards for a series of color spaces representing the visible spectrum of light. See also color space, device dependent, device independent, lab plot. Glossary 647
