Fig. 2

Chromaticities of the brightest pixels in our stimulus images, expressed as a proportion of the distance from the chromaticity of the diffuse component (IR) to the chromaticity of the illuminant (I), for the different specularities and conditions used in our experiments. The left panel shows the distributions for all three conditions of Experiment 1, since they share the same chromatic statistics. The centre and right panels show the distributions for the Bumpy and Marbled stimuli from Experiment 2. In (C), the extra series of grey boxes shows the distributions identified by selecting the centre of the highlight, rather than the brightest pixels in the images.
