1. A projection system, comprising:
an integrator with an output end;
a matrix of output windows at the output end of the integrator;
a pattern of red, green and blue monochromatic filters on the matrix of output windows passing a matrix of red, green, and blue monochromatic pixels of light;
an imager for modulating the matrix of monochromatic pixels of light; and
a light shifting device for shifting the matrix of monochromatic pixels of light to temporally form a pattern of overlying monochromatic pixels of light of different colors, viewable as a color image.
