Which color is commonly used for guidance signs that indicate directions?

Green is the color commonly used for guidance signs that indicate directions. This is because green is associated with go and positive movement, making it suitable for signs that provide directional guidance to drivers, such as exit signs on highways or directional arrows. This color helps convey information about the routes available to drivers, ensuring they can make informed decisions about their travel path.

Red, on the other hand, is typically used for stop signs and signals, which indicate prohibitions or alerts requiring immediate attention. Yellow is used for caution signs, indicating potential hazards or advising drivers to slow down. Brown signs generally convey information related to recreational areas, scenic points, or cultural sites rather than directions for navigation.
