Colorimetry - CIE 1976 L*a*b* colour space1 Scope This document specifies a method of calculating the coordinates of the CIE 1976 L*a*b* colour space, including correlates of lightness, chroma and hue. It includes two methods for calculating Euclidean distances in this space to represent the perceived magnitude of colour differences. This document is applicable to tristimulus values calculated using colour matching functions of the CIE 1931 standard colorimetric system or the CIE 1964
