Summary
This paper describes all the steps in the calculations of the CIE 1931 RGB spectral chromaticity co-ordinates and color matching functions starting from the initial experimental data of W. D. Wright and J. Guild. Sufficient information is given to allow the reader to reproduce and verify the results obtained at each stage of the calculations and to critically analyze the procedures used. In some instances, the available literature only provides limited descriptions of the actual steps in the calculations and, in others, important data were not published. Nevertheless, it has been possible to more or less reproduce the entire sequence of calculations. All the tables of numerical data are given in the accompanying computer worksheet file CIE1931_RGB.xls.
