An ink set is disclosed that comprises a first ink composition containing a first colorant, and a second ink composition containing a second colorant, wherein the first colorant is different from the second colorant; wherein each ink composition, when printed at 100% fill on the same substrate, produces a color having a hue angle, h°<SUB>n</SUB>, and a lightness relative to that of the substrate, DeltaL*<SUB>n</SUB>, according to: <?in-line-formulae description="In-line Formulae" end="lead"?>h°<SUB>n</SUB>=tan<SUP>-1</SUP>(b*<SUB>n</SUB>/a*<SUB>n</SUB>)<?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>DeltaL*<SUB>n</SUB>=L*<SUB>substrate</SUB>-L*<SUB>n</SUB><?in-line-formulae description="In-line Formulae" end="tail"?> wherein n=1 or 2 for the first and second ink compositions, respectively; h°<SUB>1 </SUB>and h°<SUB>2 </SUB>differ from each other by no more than 15°; and DeltaL*<SUB>1</SUB>>DeltaL*<SUB>2</SUB>. An ink jet printing method that employs the ink set is also disclosed, as well as a printed image prepared with the ink set.
