Paper Abstract

Random errors were propagated form tristimulus values to CIELAB and CIELUV color coordinates, using the instrumental color measurements of 28 Munsell samples illuminated by 3 light sources and performed by 3 different procedures. The errors found for the CIELAB and CIELUV color coordinates are considerably different for the 3 procedures. These errors are highest for the F source, and similar for TL84 and D65. Under our experimental conditions, we obtain that the instrumental errors for the a and b coordinates are lower than the visual subthresholds predicted by the CIE94 model.
