Color, is not only the property of the surrounding objects or surfaces, it is the sensation that is recognized by the eye and is interpreted by the brain (1). Color is created by light that affects body function as it influences mind and emotions. Collective findings have shown that color physiologically affects brain waves, functions of automatic nervous system, hormonal activity and arouses emotional and aesthetic impressions (1,2). Psychological response to color is related to subjective and objective impressions such as the perception of volume, temperature, noise and estimation of time (1,3,4). In other words, our response to color is both pyhsiological and psychological. Different hues of color with varying degrees of value and saturation arouse different feelings and associate with different moods. Studies on color connotations showed that, some colors are associated with several moods and some moods are associated with more than one color. For instance, red, symbolically known as a dominant and a dynamic color, has an exciting and stimulating hue effect . It has both positive and negative impressions such as; active, strong, passionate, warm, but on the other hand aggressive, bloody, raging and intense. Green, on the other hand, has a retiring and relaxing hue effect. It also has both positive and negative impressions such as; refreshing, quiet, natural, but also, tiresome and guilty (1,3).
