Abstract
A lighting system provides for control of the perceived color of the light emitted by the light fixture. The light fixture has two light sources, a control circuit pulses the two light sources and changes relative duty cycles of the light sources to alter a perceived color output of the lighting fixture, in response to a control signal. Duty cycles of the light sources are a function of the control signal.
