1. A method for driving a color electrophoretic display having a plurality of display pixels in an array, each display pixel being capable of displaying at least three primary colors, the method comprising:
receiving an input image;
processing the input image to define a separation cumulate at each display pixel;
defining a separation cumulate threshold array wherein each member of the separation cumulate threshold array is at least two display pixels by two display pixels in size, and includes a different separation cumulate threshold for each of the at least three primary colors; and
sending an instruction to each display pixel to display the one of the at least three primary colors corresponding to a first separation cumulate threshold that is exceeded by the separation cumulate at that display pixel.
