color and behavior

Report in the NY Times today that test subjects performance with detail and creativity were significantly affected by the room color they were in.  Red heightens our ability to deal accurately with detail.  Blue enhances creativity. Other colors affected female attractability, yellow affects hunger and thirst, red and green have other behavioral afffects.  Are these evolutionary adaptations, red associated with primitive hunting, eating, threats.  Blue associated with bodies of water, clear unthreatening sky, no data yet, only speculation.   Up until Freud exposed the hidden workings of our subterranean thoughts and emotions, the European concept of man was of a rational mind fighting with "lower" instincts.  It appears from these studies there is a part of us which subtly reacts to our environment in ways we are not conscious of and which affects our behavior.  All the time we are unaware.  How mysterious we are to ourselves, how unkown to us, we still are.
