The present invention is directed to driving methods for driving an electro-optic display device which can display high quality color states. The electro-optic display may have a plurality of display pixels, a first type of pigment particle, a second type of pigment particle, and a third type of pigment particle, wherein the three types of pigment particles have optical characteristics differing from one another, the method may include: (i) driving a display pixel to the color state of the first type of pigment particles or the color state of the second type of pigment particles; (ii) driving the pixel to a grey state between the color state of the first type of pigment particle and the color state of the second type of pigment particles; and (iii) applying at least one pair of opposite driving pulses.
