the CMY content in neutral gray shadow areas of a reproduction and
replacing them with black. As a result, the reproduction appears
normal but less process color inks are used. See also

Unsaturated color A color whose highest value is less than approximately 80%. In an
unsaturated, dirty color, the difference in the values of the wanted
colors and the unwanted color is relatively low.
For example, when the color is red, 30% cyan, 80% magenta, 70%
yellow is more unsaturated than 0% cyan, 90% magenta, 80% yellow.
