What color on a military map represents water?

The color that represents water on a military map is blue. This convention is widely used in map-making and allows for quick identification of water bodies such as rivers, lakes, and oceans. The use of blue for water is intuitive, as it closely resembles the color of water in nature, aiding soldiers in navigation and operational planning. Understanding these color codes is essential for effective map reading and situational awareness in the field. Other colors serve different purposes; for instance, brown typically denotes elevation and contour lines, green signifies vegetation and forests, and red-brown might indicate cultural features, but none are associated with water.
