A color projection system includes a light source, a polarization conversion device, a color wheel, a color separation device, and two liquid crystal light valves. The color wheel is segmented to form at least a yellow section and a magenta section, which are alternately positioned in the traveling path of the light beam. The color separation device includes a dichroic element and two color selectors. The dichroic element has a light input side, a first split-light side, a second split-light side, and a light output side, and the light beam enters the dichroic element by the light input side and leaves the dichroic element by the light output side toward a projection lens. The first and second color selectors are disposed adjacent to the light input side and the light output side of the dichroic element, respectively.
