Abstract
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.
