With digital media, it's the loss of light of certain wavelengths as it color fidelity of color images across different devices. passes through a material and is converted to heat or other forms of energy. Color spaces: A theoretical three-dimensional color system in which the axes of color, Brightness: Along with hue and saturation, an attribute of a color. It's the perceived hue, saturation and brightness are represented. quality of luminosity of a visible object. Densitometer: A tool that measures the image density (darkness) of an analog proof. A CIELAB: CIE stands for Commission Internationale de l'Eclairage, an international group transmission densitometer analyzes film.

L describes relative luminance, A represents relative redness-greenness and Grayscale: A series of shades ranging from black through white, including intermediate B represents relative yellowness-blueness. CIELAB color is a color space that encompasses grays, that contain no color. RGB and CMYK, and describes the visible spectrum that the human eye can see.

CMYK: Cyan, magenta, yellow and black, the colorants used in the four-color process of Hue: Along with brightness and saturation, an attribute of color. Hue is determined by subtractive, full-color printing. the frequency of the wave of light in the visible spectrum. Colorants: Materials such as inks, toners, pigments and dyes used by a device, primarily a International Color Consortium (ICC): The organization responsible since 1993 for the printer, to reproduce colors. standardization of profiles, or device characterizations, that contain information about the color-reproduction capabilities of devices such as scanners, digital cameras, monitors Color gamut: The range of colors that can be printed or displayed. and printers. 28 29
