Definition of color differences between two colors

This article deals with the calculation of color differences of two given colors in existing colorimetric systems of MCOs, as well as color differences obtained with the help of special formulas JRS 79, developed by the Committee on Colorimetry of the Royal Society of Dyers and Colorists (CMC) based on JRS-79, and the color difference formula recommended in 1994 by the ICE. At one time the author proposed a strictly equal-contrast color system, but in this system a rather complex mathematical apparatus based on tensor calculus is assumed. Therefore, this article proposes a simple technique for calculating color differences, using a fairly simple mathematical apparatus. The article presents the results of calculations of color differences between specific two colors. For what purpose, during the preparation of the article, a computer program was specially written that allows carrying out these calculations.
