What is BS 6923 - Calculation of small colour differences about?

BS 6923 is an international standard that discusses the method for the calculation of small colour differences. BS 6923 provides a method of calculating the colour difference between two specimens of the same material, measured under the same conditions, such that the numerical value D E , the total colour difference, quantifies the perceptibility of the colour difference or the acceptability of the colour match. The latter permits the specification of a maximum value that depends only on the closeness of the match required for a given end-use and not on the colour involved nor on the nature of the c...
