Paper Abstract

This paper describes recent developments at the National Institution of Standards and Technology in the colorimetric characterization of pearlescent coatings. The goal of this research is to develop a measurement protocol for the accurate color characterization of these coatings using an understanding of their scattering mechanism as a guide. The bi-directional reflectance of a series of samples has been measured for the visible region at incident angle of 15°, 25°, 45°, 65°, and 75° and viewing angles of +/- 80° at 5° steps. This large ensemble of measurements show general trends in the color variations with incident and viewing angles that are being used to define a preliminary subset of measuring geometries that will provide sufficient information to characterize the angle dependent color travel in pearlescent coatings.
