Text-based logos are designs that primarily use typography to represent a brand or company. These logos focus on the arrangement, style, and color of letters to create a unique visual identity. Examples include the logos of Coca-Cola and Google, which rely on distinctive fonts and colors to convey their brand messages. Such logos can be effective because they emphasize the brand name, making it memorable and easily recognizable. Text-based logos often reflect the personality of the brand, whether it's modern, playful, or professional, helping to establish a connection with the target audience.
