Counterbalancing mechanism of yellow-blue opponent-color system against macular pigment
The energy ratios of yellow to blue monochromatic lights at the yellow/blue equilibria (appearing neither yellowish nor bluish) were investigated for two color-normals along the horizontal meridian of the temporal retina and it was found that the relative energy ratios were constant at the three retinal locations investigated.
Colour appearance and compensation in the near periphery
This work examined how colour appearance changes between the fovea and near periphery by measuring achromatic loci and the loci of unique and binary hues, and found similarities in hue percepts at 0 and 8° suggest that additional processes help compensate colour appearance to maintain constancy in the near periphery.
Compensation for Light Loss Resulting From Filtering by Macular Pigment: Relation to the S-Cone Pathway
The results suggest that the visual system increases gain of the S-cone pathway to offset light absorption by MP, and this study characterizes compensation for different densities of MP.
Variant and invariant color perception in the near peripheral retina.
Hues that exhibited the largest perceptual shifts in the peripheral retina were found to correlate with intermediate hues that were equally likely to be identified by adjacent color naming mechanisms, but the correlation was found to be weakest for the green mechanism.
Unique hue judgments as a function of test size in the fovea and at 20-deg temporal eccentricity.
The results indicate that unique yellow remains approximately invariant with respect to test size and retinal eccentricity, whereas unique blue and unique green shift to longer wavelengths with increasing test size.
Color Discrimination Characteristics Depending on the Background Color in the (L, M) Plane of a Cone Space
We investigated color discriminability on the background color. The measurement was carried out at over 21 background colors in (L, M) plane of a cone space by four observers. We used low temporal
L and M cone relative numerosity and red-green opponency from fovea to midperiphery in the human retina.

Individual differences in unique yellow over a 20-nm range and the relative numerosity of L and M cones can be linked by means of this model, suggesting that the relative number of L or M cones is a factor that regulates individual variations in red-green color appearance.
Temporal Visual Mechanisms May Mediate Compensation for Macular Pigment
After assessing, in 14 subjects, MP’s effects on the temporal sensitivity of both the short-wavelength- and middle-/long-wa wavelength-sensitive visual pathways, it appears that the visual system compensates for absorption of short- Wavelength light by MP by slowing the sampling rate of short.wavelength cones and by increasing the processing speed of middle-or-long-Wavelength-sensitive cones.
A potential mechanism for compensation in the blue—yellow visual channel
Results from fMRI and psychophysical studies indicate the existence of a frequency-dependent signal amplification mechanism, whereby lower frequencies result in an amplification of S-cone signals, which could motivate a future research direction for determining the localization of blue—yellow color processing and neural compensation in the blue–yellow visual channel.


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.
Color appearance in the peripheral retina: effects of stimulus size.
The perceptive fields of the hue mechanisms at all loci were larger than anatomical estimates of the sizes of retinal receptive fields, and this increase was greater on the temporal than on the nasal retina.
Spectral sensitivity and wavelength discrimination of the human peripheral visual field.
Spectral sensitivity and wavelength discrimination are determined along the nasal horizontal meridian of the human peripheral retina and foveal wavelength discrimination is considerably better than peripheral wavelength discrimination.

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,
Color vision in the peripheral retina. II. Hue and saturation.
From a modified form of color matching, it was concluded that the color deficiency in the periphery is more tritanlike than deutanlike, strengthened by the observation, that, for small peripheral targets, hues are generally apportioned between two hue categories and the change from one to the other is at about 580 nm.
Color discrimination perimetry (A)
Color-discrimination perimetry was performed using Munsell color chips to determine how far from the fovea specific color differences would be just-noticeably different. The results show that
