A process for obtaining custom color toner compositions which comprises admixing at least two encapsulated toners wherein each toner is comprised of a core comprised of a polymer binder, pigment, dye, or mixtures thereof, and a polymeric shell; and wherein the pigment, dye, or mixtures thereof is different for each toner, thereby resulting in a toner with a color different than each of said encapsulated toners. |

DETAILED DESCRIPTION What is claimed is: 1. A process for obtaining custom color toner compositions which comprises admixing at least two encapsulated toners wherein each toner is comprised of a core comprised of a polymer binder, pigment, dye, or mixtures thereof, and a polymeric shell prepared by interfacial polycondensation polymerization; and wherein the pigment, dye or mixtures thereof is different for each toner, thereby resulting in a custom color toner with a color different than each of said encapsulated toners, and containing an effective proportion of intact polymeric shells which results in the triboelectric charge on the custom color toner being substantially equal to the triboelectric charge on the encapsulated toners. 2. A process in accordance with claim 1 wherein there are selected from about 2 to about 10 encapsulated toners. 3. A process in accordance with claim 2 wherein two passivated encapsulated toners are selected and the first toner is comprised of a core comprised of a polymer, and a cyan, yellow, or magenta pigment, and the second toner is comprised of a core comprised of a polymer, and a cyan, yellow, or magenta pigment; and wherein the pigment for the second toner is dissimilar to the pigment for the first toner. 4. A process in accordance with claim 3 wherein the pigment for the first toner is cyan, and the pigment for the second toner is magenta. 5. A process in accordance with claim 3 wherein the pigment for the first toner is magenta, and the pigment for the second toner is yellow. 6. A process in accordance with claim 3 wherein the pigment for the first toner is cyan, and the pigment for the second toner is yellow. 7. A process in accordance with claim 3 wherein the pigment for the first toner is yellow present in an amount of from about 60 to about 10 weight percent, and the pigment for the second toner is magenta present in an amount of from about 40 to about 90 weight percent. 8. A process in accordance with claim 7 wherein there results a red toner. 9
