Xerographic method and apparatus capable of achieving a very large gamut of colors using the tri-level, highlight color process. Tri-level images are formed within pixel distance of a prior developed image. These images are developed with one of two different color toners followed by recharging of the charge retentive surface and a second exposure to form more tri-level images which are selectively developed using two different color toners which are also different in color from the other toners.
