The present invention is drawn to dye sets for formulating ink-jet ink sets, and to specific ink sets. The dye set can comprise cyan colorant including a phthalocyanine dye; magenta colorant including a copper- or nickel-containing azo dye; and yellow colorant including at least one of Yellow 1189 dye and Yellow 104 dye yellow colorant having the structure Formula 1: wherein R<SUB>1 </SUB>is H, SO<SUB>3</SUB>M, COOM, or SO<SUB>2</SUB>NH<SUB>2</SUB>; and wherein R<SUB>2 </SUB>is H, SO<SUB>3</SUB>M, COOM, or SO<SUB>2</SUB>NH<SUB>2</SUB>; and wherein R<SUB>3 </SUB>is H or CH<SUB>3</SUB>; and wherein n and m are 2, 3, 4, 5 or 6; and wherein M is H, Na, Li, K, ammonium, ammonium substituted with alkyl or combinations thereof. Optionally, a cyan triarylmethine dye such as Acid Blue 9, or another similar cyan dye, can be blended with the phthalocyanine dye; a rhodamine dye can be blended with the copper- or nickel-containing azo dye; and/or Acid Yellow 17 or Acid Yellow 23 can be blended with Formula 1.
