1. A color management system comprising:

  • a switching means for achromatically switching a light beam to alternate between a first path and a second path, wherein the light beam comprises first, second and third different primary color components;

    a first color separating and routing means disposed in the first path for separating off the third primary color component, and for directing the first primary color component and the second primary color component along separate paths;

    a second color separating and routing means disposed in the second path for separating off the second primary color component, and for directing the first primary color component and the third primary color component along separate paths;

    a first imager for spatially modulating at least the first primary color components, and for outputting a first spatially modulated colored beam with a single primary color component or alternating primary color components;

    a second imager for spatially modulating two of the first, second and third primary color components, and for outputting a second spatially modulated colored beam having alternating primary color components, whereby the first and second spatially modulated colored beams together include all three primary color components;

    a beam combiner for combining the first spatially modulated colored beam with the second spatially modulated colored beam to form a projection beam.
