根据MacAdam的一个准则，对Friele 1965年提出的计算色差的MacAdam修正版本中的可调参数进行了优化，以拟合PGN实验数据。拟合的均方误差为0.030。由此产生的颜色度量系数的分布更接近PGN数据比Friele的建议的以前版本。优化后的原色的色度坐标为：红色x = 0.74054，y = 0.25946;绿色x = −1.11696，y = 2.11696;蓝色原色x = 0.13939，y = −0.03454。
The adjustable parameters in a MacAdam-modified version of Friele’s 1965 proposal for calculating color differences have been optimized, according to a criterion of MacAdam, to fit PGN experimental data. The mean-square error of fitting is 0.030. The distribution of the resulting color-metric coefficients more closely approximates those of the PGN data than do previous versions of Friele’s proposals. The optimized primaries have chromaticity coordinates of x = 0.74054, y = 0.25946 for the red; x = −1.11696, y = 2.11696 for the green; and x = 0.13939, y = −0.03454 for the blue primary.
