The color is considered as the type of non-verbal communication and the Color psychology is the study of shades as a determinant of human behavior.
UK color psychologist Angela Wright developed a means of predicting our responses to color with remarkable accuracy.
It’s called the Color Affects System and works on two levels: The psychological properties of each of the 11 basic colors; and the roles that variations in tones, hues and tints can play in achieving a desired psychological effect. A key factor in this, Angela recognized, is that it is not one color that triggers our responses, but a combination of the millions of colors, hues, tones and tints the human eye can distinguish. For example, a gray sky over a summer cornfield will evoke quite a different emotion than will a gray winter’s sky downtown. Therefore, there are no wrong colors per se, but different color schemes do prompt different responses.
