Metameric object-color stimuli involving one illuminant generally do not remain metameric when the illuminant is replaced by another. However, the different colors that occur are confined to a region of color space with a closed boundary. This boundary, called the theoretical limits of metamerism: change in illuminant, can be computed by means of a linear programing technic. The size and shape of the theoretical limits in color space depend on the illuminants involved and on the color of the metameric stimuli. A number of examples are given and some practical implications of the method are discussed.
