Abstract:

The variations in the ordering of white samples by different observers have been investigated. Twenty white samples with low to high CIE whiteness indices were prepared and ranked by 22 amateur observers and the variations in the ordering decisions of the observers were compared. Results show a significant consistency between the assessments of the observers for the white samples with low indices of whiteness. However, a large level of disagreement was found between the observers for the whiter samples. In fact, the range of ranks assigned by viewers for each sample increases with an increase in the whiteness of the specimens. Distributions of the assigned orders for the samples are interpreted by considering the CIE whiteness as well as the tinting indices.
