A logo design is the physical representation of the quality and standard of the business. It lends a face to the business and allows for an instant recognition by the customer of what to expect from a product or service. It can be a simple image such as a cup and saucer of a particular color and style, or an abstract image using one or a variety of shapes. Without words it represents the company, but it may not serve as a corporate identity for the company.
Companies often have more than one logo design. They will be similar in color and style but can be used for a variety of functions and be used independently of one another. Corporate identity logos give an idea about the company. It usually includes the colors of the company logo, the company name, sometimes the logo itself is included and possibly a tagline.
