Colors matter in the marketing world. There are brands that are initially associated by color. For instance, Target is synonymous with red and Home Depot is associated with orange. Selecting brand colors for marketing purposes sound simple, but it actually requires a lot of thought.
The concept of color affecting mood is nothing new. Ancient Egyptians and Chinese practiced chromotherapy, using colors to heal various maladies. Today's color theory, color psychology and color therapy are our modern equivalents.
