hue error
The amount of contamination in a process color pigment or ink that alters its appearance from that of a perfect process color. For example, because of yellow contamination, most magenta inks appear more red than a pure magenta ink, which is purplish red. All color separation software attempts to color correct for this error by reducing the dot sizes of the unwanted colors.
hue
The attribute of color that designates its dominant wave-length and distinguishes it from other colors. Red is a different hue than green. While dark red and bright red may have a different brightness or lightness, they may have the same hue.
