Abstract: The present invention discloses a method of improving color quality in anaglyphs. Stereo pair images are viewed using a filter of one primary color on the side corresponding to the side of the same color primary filter used in recording the anaglyph. The other side, corresponding to the side recorded using color filter of the remaining primary colors, has only a fixed or adjustable neutral density filter that matches the luminosity to that of the one primary color filter. Retinal rivalry suppresses the one primary color image on the side of the less luminous neutral density filter image, thus generating full stereopis. Since the side with the neutral density filter perceives all of the primary colors, the color gamut is maintained.
