Paper Abstract

Color and visual appearance of materials are presented within the general framework of their optical properties, described with the unique notion of complex index of refraction. We limit our investigation to materials described as homogeneous and forming a continuum at a macroscopic scale of observation, though there exist some methods for extracting optical data from spectral curves. Previous works due to John W. T. Walsh in 1926 are recalled and generalized with the help of the 3D computer simulation of the Surface of Whole Reflectivities.
