Chromatic contrast adaptation is a valuable technique for delineating cardinal and higher-order colour mechanisms. This chapter presents the results of three experiments: the first measures threshold elevation production by contrast adaptation along the cardinal axes as a function of temporal frequency at two light levels; the second investigates whether the cardinal mechanisms remain independent at these temporal frequencies and light levels; and the third measures the temporal contrast sensitivity to the cardinal mechanisms in conditions similar to those used for the first experiment. It is shown that contrast adaptation can occur at frequencies greater than 1 Hz; that the cardinal mechanisms remain independent at the temporal frequencies and light levels measured; and that contrast adaptation cannot easily be related to the temporal sensitivity of the cardinal mechanisms.

Keywords:   chromatic contrast adaptation, colour mechanisms, contrast sensitivity, cardinal mechanisms
