In many technical areas of the coloring industry, like printing, textile- and automotive industry, coloring is controlled by color measurement and color-difference evaluation. However, color-difference formulae used in practice are not well adapted to human perception. There are two formulas presented which calculate the color differences better adapted to human perception. Both formulas correct the CIE-76 formula. One of this formulas has the advantage, that it is very simple. That's why measurement results can be corrected in a simple way after measurement There is another formula given which allows including the luminance of the background in the color measurement. So far the luminance of the background was out of consideration by color measurement, although the background is very important in color vision.
