What color are directional, destination and information signs?

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

Answer: (B)

Sign readability is optimized with high contrast. Directional, destination and information signs use black letters on a yellow background. The yellow backdrop catches attention quickly, and black text provides strong contrast for legibility from a distance and at speed in varying light conditions. Other color schemes are less legible or not the standard for these signs, such as yellow letters on red background, white on black, or red on yellow.
