What color inscriptions are used for direction, destination, and information signs?

The correct answer is yellow on black backgrounds, which is the standard used for direction, destination, and information signs. This color combination is highly effective for visibility and readability, making it easier for pilots, passengers, and ground staff to quickly gather essential information. Yellow is a color that draws attention, while black provides a stark contrast that enhances legibility, particularly in bright daylight conditions commonly found at airports.

This color coding system is crucial for safety and efficiency at airports, as clear signage helps in guiding aircraft and personnel to their intended locations without confusion. Standards for airport signage are established by organizations responsible for aviation safety, ensuring uniformity across different airports, which is vital for traveler ease and operational effectiveness.
