Advertisers use psychology to attract and persuade consumers to buy products. Psychology is the scientific study of behavior and mental processes. Advertisers appeal to the unconscious, emotional part of the mind that wants immediate gratification. They also use color psychology, as color has a powerful impact on behavior and decisions. Different colors elicit different psychological responses - for example, blue is calming while red enhances physiological arousal. Marketers closely study how humans react to different colors and use this knowledge to influence consumer purchasing decisions.
