Hue, Brightness, and Saturation There are three main components to color: Hue, Brightness, and Saturation. Hue The component that determines the frequency of light or the position in the spectrum or the relative amounts of red, green and blue. Hue corresponds to the common definition of color, e.g. "red", "orange", "violet" etc. Brightness The component that determines the total amount of light (white) in the color. Zero brightness is black. 100% Brightness is white. Intermediate values are "light" or "dark" colors. Windows and Macintosh 10.3 Brightness can be adjusted when using the Gray Scale color mode (color matching method). Gray Scale: see page 253 Saturation The degree of saturation of a color is its relative purity, or freedom from, mixture with white. Windows and Macintosh 10.3 Saturation can be adjusted when using the Gray Scale color mode (color matching method). Gray Scale: see page 253 C6100 Series User's Guide 217
