What color are information signs at an airport?

1. Red

2. Yellow

3. Blue

4. Green

The correct answer is: Blue

Information signs at an airport are predominantly blue. This color choice is intentional, as blue is universally recognized for providing information and guidance. These signs play a crucial role in helping pilots, air traffic personnel, and airport staff navigate the airport environment. They indicate locations of services such as terminals, restrooms, and restaurants, ensuring that users can quickly find what they need without confusion. In contrast, other colors have different meanings: red typically signifies prohibitive actions or warnings, yellow is often used for cautionary messages, and green is usually reserved for information concerning movement areas and runways. By adhering to this color coding, airports can maintain a standardized system that enhances the efficiency and safety of operations.
