Resumen:
|
We present a discussion on the intra-observer and inter-observer variability in judging small color-differences when considering the experimental data provided by Wyszeky and Fielder. By using standard techniques in statistical theory we evaluate the size and shape of the regions of colorimetric indistinguishability in (x, y, Y) space. In the case of intra-observer variability we show that a low number of matches provides thresholds with a high degree of variation from one session to another. The analysis of data obtained for several observers reveals that thresholds vary in a non systematic way from one observer to another.
