Assimilative and non-assimilative color spreading in the watercolor configuration [PDF]
Frontiers in Human Neuroscience, 2014 A colored line flanking a darker contour will appear to spread its color onto an area enclosed by the line (watercolor effect). The watercolor effect has been characterized as an assimilative effect, but non-assimilative color spreading has also been ...

Two distinct types of color spreading induced by different luminance and color conditions in static flank transparency displays [PDF]
Frontiers in Human Neuroscience, 2023 Flank transparency refers to illusory, phenomenally transparent color spreading induced when narrow colored flanks are added to line segments located within a virtual region.

Contribution of a luminance-dependent S-cone mechanism to non-assimilative color spreading in the watercolor configuration [PDF]
Frontiers in Human Neuroscience, 2014 In the watercolor configuration composed of wavy double contours, both assimilative and non-assimilative color spreading have been demonstrated depending on the luminance conditions of the inner and outer contours (IC and OC, respectively).

Multi-layer network analysis of ACG color semantic hierarchies in digital cultural communication [PDF]
Scientific ReportsDigital color design lacks scientific guidance beyond designer intuition, limiting cultural product effectiveness. This study develops a cognitive hierarchy framework integrating feature integration, ecological perception, and cultural semiotics theories

Neon color spreading and structural information measures [PDF]
Perception & Psychophysics, 1979 This article presents a study on Van Tuijl’s (1975) neon effect. The neon effect can be described as an illusory spreading of color around the colored elements of an otherwise black line pattern. The observer has a strong impression of colored light projected onto a lattice of black lines.

Perceptual transparency in neon color spreading displays [PDF]
Perception & Psychophysics, 2002 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 displays. It was found that the data are very well accounted for by a generalization of Metelli's (1970) episcotister model of balanced perceptual transparency to

Effects of luminance contrast on color spreading and illusory contour in the neon color spreading effect [PDF]
Perception & Psychophysics, 1989 The present study examined whether color spreading and illusory contours in the neon color spreading effect of Ehrenstein figures are governed by different mechanisms. In the experiment, Ehrenstein figures with colored crosses inserted in the central gaps were used.
