Which color on a map represents water features?

• A. Blue
• B. Black
• C. Green
• D. Brown

Answer: (A)

Water features on maps are typically shown in blue. This convention makes rivers, lakes, and seas instantly recognizable and ensures good contrast with land and other features. While other colors have their own common meanings—black for man-made features and labels, green for vegetation, brown for elevation contours—the blue hue specifically signals water, making it the best choice for depicting water features.
