Abstract

Determination of the role of observer experience is of potentially critical concern regarding the development of accurate color difference formulae. As part of a larger multivariable experiment investigating the minimum inter- and intra-observer variability possible among a statistically significant set of observers, a pilot study has been conducted to compare the performance of 25 naïve vs. 25 expert visual assessors for a set of 31 pairs of colored textile samples using a controlled psychophysical grayscale method.No evidence of a training effect among the naïve observers was found using this method following three repeat assessments by each observer. However, a statistically significant difference between the judgments made by naïve and expert observers was found, demonstrating that observer experience is an important consideration in the development of visual datasets. The intra-observer variability among the naïve observers was equivalent to that of the expert assessors.
