Visual signals are forms of communication that use images, colors, or symbols to convey information. They can be found in everyday life, such as traffic signs, which help drivers understand rules and navigate safely. Other examples include warning labels on products and icons on digital devices that indicate functions or alerts. These signals rely on the ability of people to interpret visual cues quickly and accurately. For instance, the color red often signifies danger or a stop, while green typically indicates safety or go. Understanding these signals is essential for effective communication in various contexts, from road safety to user interfaces in technology.
