Logo design is part of the process of building a brand, creating the perfect visual brand mark for a company. To be more specific, it is a strategy designed for companies to help their customers identify their products and services, understand what they do, who they are and what they value and give them a reason to choose your products over the competition.
A creative Logo design is generally a combination of typographies, graphics/symbols, and colours. It is part of the visual identity of a brand.
