As a means of determining the degree of metamerism for goniochromatic objects, a generalized illuminant metamerism index for changes in spectral composition of illuminants has been formulated based on a modified LABD index. This index takes into account factors such as color memory and could be used under paramerism conditions. Consequently, a geometric metamerism and a flop index is also presented. Nevertheless, their estimation is based on the establishment of goniochromatic discrimination functions. All these concepts could be useful in many industrial‐coating applications to achieve an overall measure of variation in goniochromatism on metallic materials.
