A logo is a visual symbol or emblem representing a brand, organization, or product. It is designed to convey the brand's identity, values, and purpose in a simple yet memorable way. Effective logos are often unique, scalable, and versatile, making them recognizable across various platforms and mediums. They can include text, symbols, or a combination of both, often using colors and typography strategically. A well-crafted logo creates a lasting impression and fosters trust and connection with its audience.
