To understand what a logo is? we first must understand what the main purpose of logos is. The design process must aim to make the logo immediately recognizable, inspiring trust, admiration, loyalty and an implied superiority. The logo is one aspect of a company’s commercial brand or economic entity, and its shapes, colors, fonts, and images usually are strikingly different from other logos in the same market. Logos are used to identify. The golden ratio is the most important in logo design.
