What colors are used on location signs?

• A. Black letters on yellow background
• B. White letters on blue background
• C. Yellow letters on black background
• D. Red letters on white background

Answer: (C)

Location signs identify your current position on the airfield, not where to go. The color scheme used for these signs is yellow letters on a black background. This high-contrast combination makes the letters stand out quickly and clearly from a distance and under varying lighting, so you can confirm your taxiway or location at a glance. Different sign types use other color schemes—direction signs use black letters on yellow, information signs use white letters on blue, and mandatory signs use white letters on red—so the yellow-on-black combination specifically indicates location signs.
