A full color image containing two stages of animation where each stage is printed in complementary color components. A preselected part of the image includes no stages of animation so that the preselected part remains in perfect registration and coincidence with itself when the two stages of animation are viewed. A viewing device contains a single sheet of filter material having at least two complementary colors disposed in abutting relation to one another. The viewing device is reciprocated up and down or from left to right depending upon the embodiment to change the colors perceived by the user's eyes.
