An optical projection system is provided wherein a light valve supplies an aperture consisting of spatially separate colors for projection by a plurality of projection lenses to a projection plane. A color correction lens is placed at a selective pupil of the projection system wherein microscopic amounts of selective power are applied to at least one of the spatially seperated colors of the image at the selected pupil to cause a shift of the wavelength to bring all the wavelengths of the spatially separate colors to a common focus.
