Abstract

In order to be able to compare bronze paints with ordinary standards such as Munsell papers, it is necessary to establish conditions of illumination and viewing which will render the metallic reflection inconspicuous. It has been found that completely diffuse illumination and normal viewing are highly satisfactory, and a small integrating sphere has been constructed which enables the comparison to be carried out with relative ease. The colors of 23 samples, measured in this way, correlate closely with those calculated from measurements on a recording spectrophotometer with the specular component included.
