A logo is a graphical element (ideogram, symbol, emblem, icon, sign) that, together with its logotype (a uniquely set and arranged typeface) form a trademark or commercial brand. Typically, a logo’s design is for immediate recognition. The logo is one aspect of a company’s commercial brand, or economic or academic entity, and its shapes, colors, fonts, and images usually are different from others in a similar market. Logos are also used to identify organizations and other non-commercial entities.

Logo design is an important area of graphic design, and one of the most difficult to perfect. The logo is the image embodying an organization. Because logos are meant to represent companies’ brands or corporate identities and foster their immediate customer recognition, it is counter productive to frequently redesign logos.
