The role of color in high-level vision

Traditional theories of object recognition have emphasized the role of shap e information in high-level vision. However, the accumulating behavioral, n euroimaging and neuropsychological evidence indicates that the surface colo r of an object affects its recognition. In this article, we discuss the res earch that examines the conditions under which color influences the operati ons of high-level vision and the neural substrates that might mediate these operations. The relationship between object color and object recognition i s summarized in the 'Shape + Surface' model of high-level vision.
