A method of displaying an image in an electrophoretic display device having at least one display layer including a multiplicity of individual reservoirs containing a display fluid between conductive substrates, wherein the display fluid comprises at least two sets of particles in a liquid medium, the at two sets of particles each exhibiting a different color, wherein a first set of particles and a second set of particles have a same charge polarity and the first set of particles has a higher average charge than the second set of particles, includes applying an electric field to selected ones of the multiplicity of reservoirs to effect movement of one or more of the differently colored sets of particles in the display fluid therein to display a desired color derived from among the sets of differently colored particles, wherein the applying to display a color of the second set of particles involves pulsing an electric field through the conductive substrates for a time sufficient to attract the first set of particles away from a front viewing conductive substrate and past the second set of particles.
