The Three Attributes of Color
Hue, Density, and Saturation
The three attributes of color are hue, density, and saturation. Hue describes the
different distinguishable colors, such as red, blue, or yellow. Color variations can be
created by adjusting the hue.
The density of a color is a measure of how "bright" a color is. It describes the
brightness and darkness of colors. A higher color density area is closer to white,
whereas a lower color density area is closer to black.
The saturation of a color is a measure of how "pure" a color is. It adjusts the
vividness of colors by varying the relative strengths of white. Unsaturated colors
appear as washed out or dull, whereas saturated colors are bold and vibrant.
The colors of the spectrum are of optimal fullness and purity. Color adjustments are
thus made based on these colors.
The density and saturation of colors are interrelated. When mixing colors with
white, for example, the density becomes higher, but due to the subdued tone of the
resulting color, the saturation is lower. This relationship is summarized as the "color
tone" and the colors are described as "vivid" or "tranquil."
Color Balance Adjustment
The imageRUNNER C3100/C3100N enables you to adjust the color balance easily
by using the keys on the touch panel display. Cyan, magenta, yellow, and black can
be adjusted independently by using the Color Balance mode. In addition, the One
Touch Color mode enables you to adjust the copy's image quality (e.g., more vivid
or tranquil) with one touch of a key.
