Abstract

The Shannon entropy [Bell Syst. Tech J. 27, 379 (1948)] of spectral distributions is applied to the problem of color rendering. With this novel approach, calculations for visual white entropy, spectral entropy, and color rendering are proposed, indices that are unreliant on the subjectivity inherent in reference spectra and color samples. The indices are tested against real lamp spectra, showing a simple and robust system for color rendering assessment. The discussion considers potential roles for white entropy in several areas of color theory and psychophysics and nonextensive entropy generalizations of the entropy indices in mathematical color spaces.

  18. The unit name n-mits is intended to be short for a generalized multibase information unit. Most nongeneralized information units are “X”its where the letter replacing X describes the number used for n (e.g., bits, where b stands for binary, n=2). It is not known where or indeed whether such a general unit has previously been proposed, but it adds convenience here as it ensures 1 is always the maximum value of CESp whatever the number of wavelength intervals used.
