A continuously variable color display system includes a plurality of display areas, each including three light emitting diodes, for emitting light signals of respectively different primary colors, which are controlled by three bistable devices, respectively. Each bistable device is set at the beginning of a time interval, defined by a corresponding input digital code, and reset at the end of the time interval. Accordingly, the light emitting diodes jointly illuminate in a composite color determined by three input digital codes.
