“…Note that there is a difference in the results between these experiments. In Pungrassamee et al [22], color constancy started to decline while the appearance of the test patch was in surface-color mode. In our experiment, color constancy did not decline while the appearance of the surrounding colors was in surface-color mode and started to decline only after the luminance exceeded the luminosity threshold.…”

“…In psychophysical studies, Ikeda and his colleagues investigated the effect of surrounding surface colors on the color appearance of a high-luminance test patch in the illuminantcolor mode [21][22][23]. They measured the color appearance of a test patch in a natural scene with variable illuminations, and the results showed that color constancy gradually failed for the high-luminance test patch when the luminance became too high for it to appear as a natural object color [22].…”

“…They measured the color appearance of a test patch in a natural scene with variable illuminations, and the results showed that color constancy gradually failed for the high-luminance test patch when the luminance became too high for it to appear as a natural object color [22]. This finding suggests that color constancy applies only for test patches that appear in the surface-color mode.…”

“…In 2007 Pungrassamee et al [22] demonstrated that color constancy gradually failed for the test patch with high luminance when the color mode became an unnatural object color and then a light source color. Our result is generally consistent with theirs, except that we tested color constancy for a low-luminance test patch surrounded by high-luminance colors.…”

“…This difference might be caused by the location of the highluminance color. The high-luminance color was the test patch in Pungrassamee et al [22] but was in the surrounding colors in our experiment. Another possibility is the difference in their stimulus arrangement.…”

Theoretical and experimental approaches have proposed that color constancy involves a correction related to some average of stimulation over the scene, and some of the studies showed that the average gives greater weight to surrounding bright colors. However, in a natural scene, high-luminance elements do not necessarily carry information about the scene illuminant when the luminance is too high for it to appear as a natural object color. The question is how a surrounding color's appearance mode influences its contribution to the degree of color constancy. Here the stimuli were simple geometric patterns, and the luminance of surrounding colors was tested over the range beyond the luminosity threshold. Observers performed perceptual achromatic setting on the test patch in order to measure the degree of color constancy and evaluated the surrounding bright colors' appearance mode. Broadly, our results support the assumption that the visual system counts only the colors in the object-color appearance for color constancy. However, detailed analysis indicated that surrounding colors without a fully natural object-color appearance had some sort of influence on color constancy. Consideration of this contribution of unnatural object color might be important for precise modeling of human color constancy.

The cataract eyes can be characterized by three elements; luminance, spectral distribution, and scatter, which are perceived as brightness, color, and fogginess, respectively. Change of any of the three elements may affect visual performance. The foggy element, which refers to the perception associated with a change in the optical scatter of the crystalline lens, causes deterioration of the visual acuity, pattern perception, and an uncomfortable foggy appearance over the visual field. Moreover, it also affects the ability to discriminate and perceive colors.
