Effect of light adaptation on the perceptual red-green and yellow-blue opponent-color responses.
Spectral sensitivities of the red-green and yellow-blue opponent-color responses were determined under broad-band light adaptation for the light-adaptation levels of 5 to 5000 Td. With changing

Comparison of a Visual to a Computer Assisted Technique for Detecting Apoptosis
The computerassisted counting method of identifying the damaged DNA is more accurate and precise than the individual’s visual perception of color, and apoptosis measurements using color staining with EB and AO should be determined using hue values generated by a computer program and not by a researcher's visual assessment.


Opponent chromatic mechanisms: relation to photopigments and hue naming.
The results showed that the hue scaling was accurately predicted from the cancellation functions using the model of Hurvich and Jameson, and good linear fits were obtained for each observer's red-green curve, but not for the yellow-blue curves.
Some Quantitative Aspects of an Opponent-Colors Theory. I. Chromatic Responses and Spectral Saturation
Saturation discrimination is assumed to be dependent on the ratio of chromatic to achromatic components in the sensory response to a given wavelength. The usual methods of measurement do not,
Luminance and opponent-color contributions to visual detection and adaptation and to temporal and spatial integration.
We show how the processes of visual detection and of temporal and spatial summation may be analyzed in terms of parallel luminance (achromatic) and opponent-color systems; a test flash is detected if
Opponent-color cells can influence detection of small, brief lights
Appearance of color for small, brief, spectral stimuli, in the central fovaea.
The degree of tritanopic-like color confusions in the fovea is related to both the exposure time and the size of the test area, and the results are discussed in relation to thefoveal vs small-field characteristics of apparent tritanopia.
Effect of field size on red--green color mixture equations.
Red-green color mixture equations were measured in 10 color-normal observers for fields of view varying from 30' to 10 degrees and are consistent with the interpretation that the cone visual photopigments decrease exponentially in effective optical density as the field size is increased.
Red-Green Cone Interactions in the Increment-Threshold Spectral Sensitivity of Primates
Threshold spectral sensitivity of primate eyes is the upper envelope of the sensitivity of three response channels modeled as linear difference functions reflecting neural interaction between cones containing photopigments with 535- and 575-nanometer peaks.
