“…This is not only introspectively verifiable-it is the standard view in the literature on colour perception '' (2006, p. 84). And he notes further that in colour constancy experiments [for instance, Arend, Reeves, Schirillo and Goldstein (1991)], subjects are able to match two coloured papers for hue, saturation, and brightness even when those same two papers do not look to the subject to have the same surface colour (Thompson 2006, p. 85). to assume that in either case your experience will misrepresent the colour of the paper-in fact, we know that the visual systems of normal humans are very good at determining the unchanging colour of a surface despite changes to its ''sensory appearance.'' 9 So, once again, we have two phenomenally identical experiences of different coloured objects and yet each experience represents the colour of the relevant object veridically.…”
