Taxiway location signs have which color scheme?

• A. Yellow background with black inscription and black border.
• B. Black background with yellow inscription and yellow border.
• C. Red background with white inscription.
• D. White background with black inscription.

Answer: (B)

Taxiway location signs are designed for quick and clear identification of where you are on the taxiways. The standard color scheme is a black background with yellow inscription and a yellow border. The dark background provides strong contrast for the bright yellow letters, making the sign easy to read at a glance while taxiing. The yellow border helps the sign stand out against the pavement and surface lighting, signaling that this is a location sign rather than an instruction or direction sign. This set of colors is distinct from other signs on the airfield—mandatory instruction signs are red with white lettering, and direction signs are typically yellow with black lettering—so pilots can immediately recognize the type of information each sign conveys.
