Abstract: According to exemplary methods, a processor of a printing device determines color values out of a first colorant combination using marking materials for standard colorants and marking materials for one or more extended gamut colors. The extended gamut color has colorants other than the standard colorants. Responsive to the first colorant combination including color values for each of a pair of two complementary colors, the processor calculates a second colorant combination that produces the same human-perceivable color as the first colorant combination. The second colorant combination includes only one color of the pair of two complementary colors. The printing device produces output using the second colorant combination for the standard colorants and the extended gamut color.
