Brand identity is how your business presents itself to the world. It includes visuals like logos, colors and fonts, as well as your mission, values, personality and voice. Brand identity ties together visuals and messaging to create a clear and lasting impression.
A logo is a mark that helps identify a business. Just like a signature identifies a person, a logo lets people instantly recognize a company. It is the focal point of every brand and the first thing people notice.
Visual identity is everything people see about your business. The logo, colors, fonts, images, patterns and illustrations that make your brand look consistent everywhere.
The full package: everything visual, plus the thinking behind it.
Each level contains the one before it. If you only need a mark, start with the logo. If you need to look consistent everywhere, take the visual identity. If people still would not be able to say what you stand for, you need the full brand identity.
