Our personal and cultural associations affect our experience of color. Colors are seen as warm or cool mainly because of long-held (and often universal) associations. Yellow, orange and red are associated with the heat of sun and fire; blue, green and violet with the coolness of leaves, sea and the sky. Warm colors seem closer to the viewer than cool colors, but vivid cool colors can overwhelm light and subtle warm colors. Using warm colors for foreground and cool colors for background enhances the perception of depth.
Although red, yellow and orange are in general considered high-arousal colors and blue, green and most violets are low-arousal hues, the brilliance, darkness and lightness of a color can alter the psychological message. While a light blue-green appears to be tranquil, wet and cool, a brilliant turquoise, often associated with a lush tropical ocean setting, will be more exciting to the eye. The psychological association of a color is often more meaningful than the visual experience.
Colors act upon the body as well as the mind. Red has been shown to stimulate the senses and raise the blood pressure, while blue has the opposite effect and calms the mind. People will actually gamble more and make riskier bets when seated under a red light as opposed to a blue light. That's why Las Vegas is the city of red neon.
For most people, one of the first decisions of the day concerns color harmony. What am I going to wear?

Color is light and light is energy. Scientists have found that actual physiological changes take place in human beings when they are exposed to certain colors. Colors can stimulate, excite, depress, tranquilize, increase appetite and create a feeling of warmth or coolness. This is known as chromodynamics.
An executive for a paint company received complaints from workers in a blue office that the office was too cold. When the offices were painted a warm peach, the sweaters came off even though the temperature had not changed.
