Color in one’s environment is known to bring emotional, social, and physiological reactions to people. Despite its significance, understanding meaning of color in environments is challenging mainly because of the difficulty in testing real color environments with virtually unlimited possible color combinations. As the context of color usage changes its impact on human responses, studying color ...

Colors and their relationship to surrounding colors cause observers to feel specific emotions. This study proposes a method for extracting emotional words from the color combinations within images. For this, we extract the color spectrum of an input image. By examining the extracted color spectrum and color combinations, we obtain an emotional word. Then, we determine a specific emotion conveye...

The effect of harmonious versus non-harmonious color combinations in one aspect of information visualization effectiveness is considered. One focus is the relative suitability of two competing paradigms for determining color combinations that are harmonious. A second focus is the suitability of using opposing (i.e., opponent) colors for feature presentation in information visualization. The eff...

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 tristimulus values. This additive model co...

Color harmony is an important factor for image aesthetics assessment. Although plenty of color harmony theories are proposed by artists and scientists, there is little firm consensus and ambiguous definition amongst them, or even contradictory between them, which causes the existing theories infeasible for image aesthetics assessment. In order to overcome the problem of conventional color harmo...

Observing paired colors with a different hue (in terms of chroma and lightness) engenders pleasantness from such harmonious combinations; however, negative reactions can emerge from disharmonious combinations. Currently, neural mechanisms underlying the esthetic and emotional aspects of color perception remain unknown. The current study reports evidence regarding the neural correlates of color ...

Test targets ('singletons') that displayed orientation, motion, luminance, or color contrast, or pairwise combinations of these, were presented in line texture arrays, and their saliences were quantified in comparison to reference targets at defined luminance levels. In general, saliency effects in different stimulus dimensions did add, but did not add linearly. That is, targets with feature co...
