What color is used to identify restricted areas on a map?

• A. Blue
• B. Green
• C. Red
• D. Yellow

Answer: (C)

Red is used to flag restricted areas because it stands out against the map’s natural colors and signals a clear warning. This contrast makes it easy to recognize zones where access is limited or prohibited, which is crucial for safety and mission planning. Other colors serve different purposes: blue marks water features, green shows vegetation, and yellow/other tones indicate built-up or non-restricted areas, so they don’t carry the same immediate prohibition cue. When you encounter red on a map, treat that area as restricted and plan accordingly or obtain the necessary authorization before proceeding.
