Abstract

In anomalous trichromacy the spectral sensitivities of the two cone types sensitive in the long and medium wavelength part of the spectrum overlap to a much greater degree than in normal colour vision. Consequently, discrimination of colour differences in that part of the spectrum is typically reduced from normal. However, suprathreshold colour perception may be relatively spared by postreceptoral compensation, in which colour signals would be enhanced postreceptorally to fill the range of possible neural signals. Alternatively, colour signals may be enhanced by inserting a notch filter that removes light in the region of spectral overlap of the two cone types present in anomalous trichromacy. Evidence will be considered for and against the effectiveness of these two potential strategies for boosting anomalous colour vision.
