Dark Colors, such as those at the bottom of the box to the right, lower stress and increase feelings of peacefulness.

Bright Colors such as red, orange, yellow and those in the middle third of the box spark energy and creativity. They may also increase aggressive and nervous behavior.

For optimal learning, choose yellow, light range, beige, or off-white, such as those at the top of the box.   Those colors seem to stimulate positive feelings.
The Power of Color
Red is an engaging and emotive color and best for restaurants. It is considered more disturbing by anxious subjects, and more exciting by calm subjects. It triggers the pituitary and adrenal glands and releases adrenaline. It also may increase blood pressure and breathing, and stimulate appetite and sense of smell.

Yellow is the first color a person distinguishes in the brain. It is associated with stress, caution, and apprehension, yet it stimulates an overall sense of optimism, hope, and balance.  It is also excellent for use in classrooms.


Orange has the characteristics halfway between red and yellow. It is one the best colors for stimulating learning.


Blue is the most tranquil color. It calms tense subjects and increases feelings of well-being. When you see blue, your brain releases eleven neurotransmitters that relax the body, and may result in a reduction of temperature, perspiration, and appetite. Blue may be a bit too calming for most learning environments.

Green is also a calming color. In response to this color, blood histamine levels may rise resulting in reduced sensitivity to food allergies. Antigens may be stimulated for overall better immune system healing.



Brown promotes a sense of security, relaxation, and reduces fatigue.



Gray is the most neutral color.
