Abstract

Logvinenko & Maloney (2006) previously demonstrated that surface albedo and lighting intensity both contribute to rated dissimilarity in lightness when surfaces are viewed under different illuminants. We extend these results to dissimilarity of coloured surfaces under neutral illuminants that differ in intensity. Observers saw three spatial arrays each containing seven Munsell papers. Each array was illuminated independently with intensity 6, 110, or 2100 lux. Subjects judged the dissimilarity of all possible pairs of surfaces. Two methods - quadruple comparisons, and ranking – were used. The resulting MDS solutions showed separable effects of hue and light intensity. The effect of change in illumination was to scale down the output configuration: decreased intensity corresponded to decreased dissimilarities.
