Abstract: The discrepancy between the relative brightness and the relative luminance of two lights, one much more highly saturated than the other, is found to decrease markedly over a period of 2-3 min of steady fixation. This finding suggests temporal differences in the adaptive characteristics of chromatic and achromatic visual channels. When the eye has become adapted to the test field, the brightness-luminance discrepancy can be revived to some extent by introducing modest perturbations in the luminance of the relatively unsaturated light. Failure to control the temporal variable could be a major source of the differences, both from subject to subject and within the same subject, often found in heterochromatic brightness matching.
