Abstract

A visual assessment of the luminosity of 22 different samples of daylight fluorescent pigments has been carried out by the method of paired comparisons. From these investigations, it can be concluded that a linear relationship exists between the sensation of luminosity and the calorimetric quantity Λ = Yfl/Y+aY+bpe, which has previously been suggested for characterizing the luminosity of daylight fluorescent pigments. Y is the luminous reflectance of the color, pe is its excitation purity, Yfl is the luminous reflectance of the fluorescent light of the sample, and a and b are constants.
