Abstract

The aim of the project is to elucidate the mechanisms underlying three kinds of human colour constancy: illuminant, displacement, and relational colour constancy. Psychophysical and theoretical work will be undertaken using computer-controlled colour-graphics displays with high spatial and chromatic resolutions. A set of interrelated questions will be addressed, including how spatially distributed colour information is integrated visually; what bias there is on constancy performance due to environmental variations in the densities of spectral reflectances; how scene segmentation affects visual constancy; whether detecting reflectance changes is a preattentive visual function; what kinds of visual pathway mediate information about violations in colour constancy; and what the impact is on colour constancy of losing one or more cone-receptor classes.
