Color and Mood....

Color is a powerful communication tool and can be used to signal action, influence mood and affect the body and how it reacts.  Some colors have been associated with increased blood pressure, increased energy and with eyestrain.
The color red (please stay away from that charging bull), orange, and yellow are know as the warm colors.  They can evoke feelings of warmth and comfort, to feelings of anger and hostility.
Colors on the blue, purple and green spectrum can be described as calming or of indifference and sadness.
Unless your color blind.....

Well, LENS is good at helping to heal the brain so that you can see colors better.  I have had people walk out of the room and see the sky and trees as they never have in the past.  It creates a clearer, calmer brain.
