    Abstract: A composite color includes a first colored ink and a second colored ink. The first colored ink exhibits a color that is different from that exhibited by the second colored ink. The first colored ink includes pigment particles either formulated at a basic pH so that a surface of the pigment particles carries a net negative charge or formulated at an acidic pH so that a surface of the pigment particles carries a net positive charge; and the second colored ink includes pigment particles either formulated at an acidic pH so that a surface of each of the pigment particles carries a net positive charge or formulated at a basic pH so that a surface of the pigment particles carries a net negative charge. The first colored ink and the second colored ink have opposite charges. The composite color exhibits enhanced color richness when printed on a substrate.
