A color image projecting apparatus having three cathode ray tubes which produce different respective color images and including two projecting lenses. A first primary color image reproduced on a first cathode ray tube is projected on a screen through a first projecting lens, and second and third primary color images reproduced on second and third cathode ray tubes, respectively, are synthesized by a dichroic mirror and then projected on the screen through a second projecting lens. In this case, the projecting axes of the first and second projecting lenses are arranged to converge two images passed therethrough on the screen.
