“…Originally these shifts were reported using spectral lights superimposed on a black or neutral background (e.g., [5]). Subsequent measurements have been performed on computer monitors, and qualitatively the same results have been obtained [19]. In this study, we have presented data from two control experiments that highlight two main findings: first, the hue distortions exhibited by real-world color stimuli exhibit the same perceived hue shifts as stimuli generated on a computer monitor when viewed peripherally.…”

Certain hues undergo shifts in their appearance when they are viewed by the peripheral retina. This has often been shown on a 3-primary color CRT monitor. To investigate the possible role of metamerism, we replicated our peripheral color matching experiments using Munsell paper stimuli viewed under real and simulated daylight (using a 3-primary projection system). Using stimuli of constant value and chroma (7/4), observers adjusted the hue of a 3 deg target presented 18 deg nasally, until it matched a 1 deg target presented 1 deg nasally. The magnitude and pattern of measured hue shifts were similar to those measured using CRT stimuli. We conclude that the perceived hue shifts that have previously been reported in the peripheral retina are independent of the nature of the stimulus and of the illuminant.

“…However, on a qualitative level they can be simply described as shifts toward blue (in the case of pink, purple, and cyan) or toward yellow (in the case of green and orange). Previous studies have noted a similar bias toward blue and yellow in the peripheral retina 11,24,27,29,[47][48][49][50] and have attributed the shift to a number of possible causes, such as changes in the weightings of cone inputs 10 and increasing rod influence, 29 for example. Regardless of the basis of these hue shifts, they appear to indicate a shift in the relative predominance of the blue-yellow over the red-green op- a Comparisons between the hues identified as unique in the color naming experiments and those that exhibited zero shifts in hue with eccentricity in the asymmetric color matching experiments.…”

Perceived shifts in hue that occur with increasing retinal eccentricity were measured by using an asymmetric color matching paradigm for a range of chromatic stimuli. Across nine observers a consistent pattern of hue shift was found; certain hues underwent large perceived shifts in appearance with increasing eccentricity, while for others little or no perceived shift was measured. In separate color naming experiments, red, blue, and yellow unique hues were found to be correlated with those hues that exhibited little or no perceptual shift with retinal eccentricity. Unique green, however, did not exhibit such a strong correlation. 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. However, once again the correlation was found to be weakest for the green mechanism. These data raise the possibility that perceptually unique hues are linked to color signals that represent the most reliable (minimally variant) chromatic information coming from the retina.

“…Human colour perception in the peripheral retina has been found to be different from that experienced at the fovea (Moreland and Cruz, 1959;Abramov et al, 1991;Nerger et al, 1995;Ayama and Sakurai, 2003;Parry et al, 2006;McKeefry et al, 2007). One possible reason for this is that in the peripheral retina there are losses in cone opponent function.…”

We recorded L- and M-cone isolating ERGs from human subjects using a silent substitution technique at temporal rates of 12 and 30 Hz. These frequencies isolate the activity of cone-opponent and non-opponent post-receptoral mechanisms, respectively. ERGs were obtained using a sequence of stimuli with different spatial configurations comprising; (1) circular stimuli of different sizes which increased in 10° steps up to 70°diameter, or (2) annular stimuli with a 70° outer diameter but with different sized central ablations from 10° up to 60°. L- and M-cone isolating ERGs were obtained from five colour normal subjects using a DTL fibre electrode. Fourier analysis of the ERGs was performed and we measured the amplitude of the first harmonic of the response. For 12 Hz ERGs the L:M cone response amplitude ratio (L:M(ERG)) was close to unity and remained stable irrespective of the spatial configuration of the stimulus. The maintenance of this balanced ratio points to the existence of cone selective input across the human retina for the L-M cone opponent mechanism. For 30 Hz the L:M(ERG) ratio was greater than unity but varied depending upon which region of the retina was being stimulated. This variation we consider to be a consequence of the global response properties of M-cone ERGs rather than representing a real variation in L:M cone ratios across the retina.
