Color coding is a system that uses different colors to organize and categorize information. This method helps people quickly identify and understand various elements, making it easier to find what they need. For example, in a calendar, different colors can represent different types of events, such as work, personal, or holidays. In addition to calendars, color coding is commonly used in files, documents, and even clothing to streamline organization. By assigning specific colors to particular categories, individuals can enhance their productivity and reduce confusion, allowing for a more efficient way to manage tasks and information.
