Several years ago, the makers of M&Ms - an American candy that contains an assortment of different colored chocolate sweets -added a new color to its candy bag: Blue. Blue ? Why Blue? Although they reported that this was the result of a vote by M&M's fans it raises a few questions. It may very well be the last color left in the bag after the novelty wears off. You may have done a color analysis at one time to determine what color wardrobe you look best in. But have you thought about how colors affect the way we feel about the food we eat? Color psychology has been used in marketing for a long time.
