Have you ever wondered why products come in the colors they do? For instance, why is toothpaste often green or blue and shampoo often golden-yellow? Manufacturers pick the colors that are associated with qualities consumers value in certain products. For example, it's known that blue symbolizes purity to most people and that green is refreshing. These are both desirable qualities in toothpastes. Manufacturers also know that golden-yellow symbolizes richness (as in real gold or egg yolks), so they frequently choose this color for shampoos and cream rinses-products in which consumers value richness. Baby products, such as body lotion, are often tinted pink because that is a color commonly associated with softness and gentleness-the very qualities consumers want their baby's care.
