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,...

background: colors make many problems and these are major sources of environmental pollution. therefore, this wastewater should be treated before discharge to environment to reduce the environmental threats. adsorption is one of the usual processes for color removal from wastewater. nanotube s are new adsorbents with extend application for adsorption of different compounds. aim of this study wa...

this study evaluates the effects of spirulina (arthrosphia maxima) and carrots (daucus carota) powder on body color changes of 330 pseudoteropheus zebra with average 15 g initial weight, in 35 days experimental period. as the results showed, the best content of steamed carrot in wet diet was 20 %, and all the factors except background color showed significant differences with control treatment ...

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...

Color constancy is something we take for granted. An apple appears red despite monumental changes in the intensity and spectral balance of illumination. There are many components to human visual system that make this illusion possible. Nonetheless, imperfect. Objects will change apparent color under different The CIELAB space allows computation values any illuminant. will, general, as illuminan...

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...

Pressure to force or induce the consolidation of rural schools through legislation is common across the United States. Whereas consolidation was once chiefly about school improvement, today it is more likely to be about fiscal savings. Legislative battles have produced many lessons for rural school advocates which are discussed here. Consolidation is also on the agenda of many of the school ref...

Originating in the grapes, monomeric anthocyanins in young red wines contribute the majority of color and the supposed beneficial health effects related to their consumption, and as such they are recognized as one of the most important groups of phenolic metabolites in red wines. In recent years, our increasing knowledge of the chemical complexity of the monomeric anthocyanins, their stability,...

The current paper provides methods to correct the artifact known as “red eye” by means of digital color image processing. This artifact is typically formed in amateur photographs taken with a built-in camera flash. To correct red eye artifacts, an image mask is computed by calculating a colorimetric distance between a prototypical reference “red eye” color and each pixel of the image containing...
