Abstract

The problem of determining color distance between two arbitrary colors is considered. The color solid is assumed to be a riemannian space so that small color differences can be described by a quadratic form in the three-dimensional color space. The geodesics and the corresponding distances are generated by a steepest-descent method with fast convergence and small storage requirements on the digital computer. The results are illustrated by means of tables and graphs.
