On a Possible Contribution to the Colour Sense by the Blur Circles on the Human Retina Caused by Chromatic Aberration

Abstract

Theories of colour vision at the receptor and neurological level, while probably sound, could be made more plausible by the existence of the system processing colour cues available in the retina. One such cue could be chromatic aberration. Using an anomaloscope colour perception was adversely affected by the absence of chromatic aberration. Two groups of 16 subjects provided data.
