Abstract

Larimer and Piantanida investigated hue cancellation for red-green increments flashed on chromatic adapting fields consisting of a center disk with annular surround. The disk/annulus boundary was either stabilized or not, and thus the disk could have the color appearance of the annulus or not. They found that, in some conditions, the appearance of the disk, rather than its actual wavelength composition, determined the red-green ratio at which the increment appeared uniquely yellow. The appearance of an adapting field can also be altered by means of binocular fusion. Our study, part of which replicates the work of Humanski and Shevell, examined hue cancellation with red-green or blue-yellow increments on either monocular adapting fields or fused binocular adapting fields. Stimuli were presented on a color monitor driven by a microcomputer. Results show that the hue-cancellation functions cannot be simply related to the composition of the monocular adapting field, the color appearance of the fused adapting field, or the additive effect of the dichoptic adapting fields.
