S. Nishida and M. Shinya (1998) found that observers have only a limited ability to recover surface-reflectance properties under changes in surface shape. Our aim in the present study was to… Expand
Color appearance: The limited role of chromatic surround variance in the "gamut expansion effect".
R. O. Brown and D. I. MacLeod (1997) observed that chromatic patches appear much more saturated against an equiluminant, uniform gray surround than against a chromatically variegated surround with… Expand
Transparency perception: the key to understanding simultaneous color contrast.
The well-known simultaneous color contrast effect is traditionally explained in terms of visual color constancy mechanisms correcting for the confounding influence of ambient illumination on the… Expand
Classification of apparent motion percepts based on temporal factors.
As pointed out by M. Wertheimer (1912), a number of qualitatively different motion impressions, such as "optimal motion," "part motion," and "pure phi," may be evoked by manipulating the temporal… Expand
Psychophysical model of chromatic perceptual transparency based on substractive color mixture.
Variants of Metelli's episcotister model, which are based on additive color mixture, have been found to describe the luminance conditions for perceptual transparency very accurately. However, the… Expand
The peculiar nature of simultaneous colour contrast in uniform surrounds
We present evidence from asymmetric colour matching experiments which strongly suggests that uniform surrounds evoke induction effects of a very peculiar nature, not representative of colour… Expand
A simple model describes large individual differences in simultaneous colour contrast
We report experimental evidence for substantial individual differences in the susceptibility to simultaneous colour contrast. Interestingly, we found that not only the general amount of colour… Expand
Perceptual transparency in neon color spreading displays
In neon color spreading displays, both a color illusion and perceptual transparency can be seen. In this study, we investigated the color conditions for the perception of transparency in such… Expand

Although current theories of color vision differ in many respects, they all assume the existence of a uniquely defined neutral point in chromaticity space. It generally is assumed that this point… Expand
Basic Characteristics of Simultaneous Color Contrast Revisited
In this article, we present evidence supporting the hypothesis that the local mechanism of simultaneous color contrast is the same as the mechanism responsible for the crispening effect and the gamut… Expand
