<p>The present invention is directed to color tuning methods for electrophoretic display devices. For example, a color tuning agent may be added to a composition for forming a display cell structure or a primer layer. Alternatively, a separate color tuning layer may be added to a display device. Further, a color tuning agent may be added to an electrophoretic display fluid. The color tuning methods are useful for adjusting the color temperature of a display device.</p>
