Method for designing color display sequences in a display system using rapidly switching light sources. A preferred embodiment comprises determining a number of bit segments in a frame time, determining a color sequence, and specifying a bit sequence from the color sequence. The bits in the bit sequence are delineated by a switching of a rapidly switching light source or a state change of a light modulator. The use of the rapidly switching light source can permit the specification of bits that are shorter than a minimum duration of a state change of the light modulator and the possible elimination of a segmented color filter that can enable adjustments to the color point of the display system to meet changing operating conditions.
