Branding involves using names, symbols, or designs to identify and differentiate the goods and services of one seller from others. There are different types of branding including personal branding, corporate identity, and rebranding. Corporate identity expresses an organization's personality through communication, behavior, design, and what employees wear. It also defines how an organization communicates with clients. Strong identities are built through powerful logos that are simple, scalable, suitable for the industry, and strong without colors. Color psychology studies how color impacts human behavior and emotion.
