Study of Observer Variability in Modern Display Colorimetry: Comparison of Cie 2006 Model and 10° Standard Observer

This paper compares CIE 2006 model predictions and the 1964 10° standard colorimetric observer with the average observer data from three distinct subgroups of 47 Stiles-Burch observers formed on the basis of observer ages. For two of these subgroups, the long-wave sensitive (x-) color matching functions obtained from the CIE 2006 model did not accurately predict the intra-group average observer functions. In terms of display color perception, the prediction error is reflected in the longer wavelengths of the color spectrum. In contrast, the short-wave sensitive (z-) function of the 10° standard observer showed significant deviations from the intra-group average observer for all three subgroups.
