Sorry, I could not get my keyboard to stay up to leave a comment to the original post. There actually ARE professionals that deal with the psychology of marketing and colors. You can learn quite a bit by just Googling these words. Colors have a huge influence on the human psyche and how we react to them. Just look at any election campaign ad! And the colors you use may be more positively received in one area of the U.S. versus another area. Look at Sotheby's realty signs...tastful, blue & white. Conveys professionalism and quiet success. They don't "scream" at you. They are on every For Sale home in Princeton, NJ, but not that many in Silver Spring, MD. Just Google the subject!
