This is a book about color and people. It has been written to be of practical benefit to modern business, to assure the effective development of consumer products, merchandising, advertising, packages, displays. Most books on color will be found long on theory and short on practice. This, perhaps, is because color is emotional in its appeal and tends to inspire a personal and subjective viewpoint. Yet while the so-called artistic aspects of color may be elusive, the facts of mass human reaction are/ otherwise. For color in industry today may be engineered with remarkable certainty, once the methods are known and applied with intelligence and care. It is evident that when you pick the right colors you sell a lot of merchandise or in?uence a lot of people; when you pick the wrong colors you pile up unsold inventories and see the public turn its back. To management this means that color problems must be rightly analyzed and estimated, that customers and markets must be known.
