The relative salience of the cardinal axes of colour space in normal and anomalous trichromats

By imposing rival perceptual organizations on a regular spatial array, we have measured the relative salience of colour differences along the two cardinal axes of colour space. Results are reported for normal and anomalous trichromats. For most, but not all, anomalous trichromats S cone modulations are relatively more salient than they are for normal trichromats. The spatial separation of the elements of the array has a major effect on its perceptual organization.
