title: Red-green opponency in the detection and the perceptual hue cancellation.
abstract: We show how the red-green antagonism in the detection process is related to the red-green antagonism in the hue cancellation. By measuring the incremental redness or greenness thresholds for bichromatic mixtures, the red-green antagonism was determined at color threshold and in the perceptual hue cancellation. By measuring the detection threshold for bichromatic mixtures, the red-green antagonism was determined at detection threshold. There was agreement among the red-green antagonisms at detection threshold, at color threshold and in the perceptual hue cancellation.
