This relationship is believed to be a consequence of the patient's expectations and not a direct effect of the color itself. Consequently, these effects appear to be culture-dependent.

Use of color to create ambiance

Color has long been used to create feelings of coziness or spaciousness. However, how people are affected by different color stimuli varies from person to person.

The hues in the blue range have been shown to have the highest preference amongst people.

There is evidence that suggests that people tend to prefer certain colors depending on the ambient temperature. People who are cold prefer warm colors like red and yellow while people who are hot prefer cool colors like blue and green.

Studies have shown that colors have an effect on people's moods and emotions. One problem that exists is that these studies are inconsistent on determining which colors bring out or reflect specific moods and emotions. In other words, the relationship between color and behavioral response exists but there hasn't been any consistency as to how it exists.

Some research has concluded that women tend to feel pleasant seeing "warm" colors while men tend to feel pleasant seeing "cool" colors.

A few studies have shown that cultural background has a strong influence on color preference. These studies have shown that people from the same region regardless of race will have the same color preferences. Also, one region may have different preferences than another region (i.e., a different country or a different area of the same country), regardless of race.

Children's preferences for colors they find to be pleasant and comforting can be changed and can vary, while adult color preference is usually non-malleable.

Light, color, and surroundings

Light and color can influence how people perceive the area around them. Different light sources affect how the colors of walls and other objects are seen. Specific hues of colors seen under natural sunlight may vary when seen under the light from an incandescent (tungsten) light-bulb: lighter colors may appear to be more orange or "brownish" and darker colors may appear even darker. Light and the color of an object can affect how one perceives its positioning. If light or shadow, or the color of the object, masks an object's true contour (outline of a figure) it can appear to be shaped differently than it really is. Objects under a uniform light-source will promote better impression of three-dimensional shape. Although more evidence is needed, it is believed that the color of objects can affect how one perceives their motion. Under a uniform light source objects of different color can more easily be seen moving in different directions. However, under variable light sources, which are more often encountered, the motion of objects can be masked or not perceived as easily because one's mind is preoccupied with trying to differentiate the contour and color of the objects.
