Simplified match formulation for fluorescent color specimens

Match formulation for fluorescent color specimens is much more difficult than for nonfluorescent color specimens, because both the reflected radiation and the fluorescent radiation must be taken into account. A simple method is described that allows match formulation for fluorescent colors within a small region around an initial color. This method uses a correction matrix and tries to minimize the differences in x, y, and Y and not the differences in the spectral radiance factors. The calculated match formulae are composed of four components, which can be fluorescent or non‐fluorescent enamels. The mode of operation of the method described is demonstrated for green, yellow, and red fluorescent color specimens.
