Brown

Brown is a warm neutral color that can stimulate the appetite. It is found extensively in nature in both living and non-living materials. People who prefer brown are often conventional and orderly. The negative meaning of brown can be a repressed personality or a lazy person. Brown is the color of the earth and is associated with the material side of life.

Brown represents wholesomeness and earthiness. While it might be considered a little on the dull side, it also represents steadfastness, simplicity, friendliness, dependability, and health. Although blue is the typical corporate color, UPS (United Parcel Service) has built their business around the dependability associated with brown.

Fun Fact: It is said that people who have brown auras are often unethical businessmen who are in business purely for the sake of greed, or people who are just generally greedy and avaricious
