What color indicates a Taxiway Directional Sign?

A taxiway directional sign is specifically designed to provide guidance to pilots and vehicle operators on the airport's airside. The standard color for taxiway directional signs is yellow with black letters. This color scheme is utilized because yellow is highly visible and stands out against various backgrounds, allowing for easy recognition and readability from a distance. The black lettering further enhances visibility, ensuring that important directional information can be communicated effectively to users navigating the taxiways.

Understanding this standard is crucial for maintaining safety and efficient movement in the complex environment of an airport, where clear and distinct signage is essential for coordinating aircraft and vehicle operations.
