Visual signals are forms of communication that use images, colors, or symbols to convey messages. They can be found in everyday life, such as traffic lights, which use red, yellow, and green to indicate when to stop, slow down, or go. Other examples include signs, like stop signs or warning signs, that help people understand important information quickly and effectively. In nature, many animals use visual signals to communicate with each other. For instance, peacocks display their colorful feathers to attract mates, while fireflies use light patterns to find partners. These visual cues are essential for survival and reproduction, helping creatures convey their intentions without using sound.
