The arousal theory of color proposes that red is associated with arousal. Research on the color-in-context theory, in turn, states that the context in which red is perceived influences its valence-related meaning and behavioral responses to it. This study faces and integrates these theories by examining the influence of red on both arousal and valence perceptions of test-relevant and neutral st...

In visual search for a conjunction it is much more difficult to search for the conjunction of 2 colors or 2 orientations than for Color x Orientation or Color x Shape conjunctions. The result is not limited to particular colors or shapes. Two colors cannot occupy the same spatial location in Color x Color searches. However, Experiments 6 and 7 show that Color x Shape searches remain efficient e...

Recent research indicates a direct relationship between low-level color features and visual attention under natural conditions. However, the design of these studies allows only correlational observations and no inference about mechanisms. Here we go a step further to examine the nature of the influence of color features on overt attention in an environment in which trichromatic color vision is ...

The color psychology literature has made a convincing case that color is not just about aesthetics, but also about meaning. This work has involved situational manipulations of color, rendering it uncertain as to whether color-meaning associations can be used to characterize how people differ from each other. The present research focuses on the idea that the color red is linked to, or associated...

Both evolutionary considerations and recent research suggest that the color red serves as a signal indicating an object's importance. However, until now, there is no evidence that this signaling function of red is also reflected in human memory. To examine the effect of red on memory, we conducted four experiments in which we presented objects colored in four different colors (red, green, blue,...

The removal of color from synthetic wastewater containing Congo red was experimentally investigated using electrocoagulation process. The effects of operational parameters such as current density, electrolysis time, electrolyte concentration, electrode distance, initial dye concentration, initial pH and temperature on color removal efficiency were investigated in this study. The tentative resul...

The aromas and flavours of Cabernet Sauvignon wines originating from Australia are diverse and known to display ‘berry’, ‘current’, ‘vanilla’, ‘fruity’, ‘caramel’, ‘green’ and ‘capsicum’ aromas and ‘blackcurrant’, ‘green capsicum’, ‘vanilla’, ‘mulberry’ and ‘mint’ flavours (Green 2000, Gurbuz et al. 2006). These wine aromas and flavours can range in fruit-related characteristics of ‘berry’, ‘sp...

One of the outstanding features of polycythemia vera is the color of the skin. Clinical descriptions employ the terms brick red, congestive facies, cyanosis and erythrosis. Vaquez, who reported the first observed case of this disease, noted cyanosis as the prevailing tint. Osler thought that the color change was not that of cyanosis but congestion or redness. Since the microscopic investigation...
