This book is a fascinating and intelligible story about the role that color plays in our lives. Although its influence on the psychology, physiology, behavior, mood and even physical fitness of a person has been known for a long time, recently it has received particularly close attention. It turned out that color excites and calms, stimulates productivity and creative thinking, affects our perception of smells and tastes, encourages us to bargain and buy. Today, not only artists and designers enjoy the widest possibilities of color. Its enormous potential is realized in pharmacology, the food industry, perfumery, trade, medicine... Jean-Gabriel Causse introduces the reader to the nature of color and the countless possibilities of its use.
