A method and apparatus is described for permitting human perception of more of the spectrophotometric values which define the color of an observed object. In eyeglasses a first optical filter, worn over the left eye, is provided having a spectral response (31) containing three peaks; one for each of red, green, and blue, tuned to the maximum responsiveness of the human eye to red, green, and blue colors. A second optical filter, worn over the right eye, is similar to the left optical filter, but has a response (37) with the peaks tuned to complementary portions of the visual spectrum. In this manner, a dimension of color perception is added, because each eye sees different colors for the same object which when combined represent the actual color of the object. The filters are visually neutral to white light. The eyeglasses may be applied to color matching or two distinguishing colors which appear the same to the unaided eyes. <IMAGE>
