Which color on a map is used to indicate water features?

On a map, water features such as lakes, rivers, and other bodies of water are represented by the color blue. This convention is widely recognized and helps users easily identify aquatic elements in relation to land areas. The use of blue for water is intuitive, as it resembles the natural color of water and creates a clear distinction from land features.

In contrast, brown is typically used to depict elevation changes or landforms, such as mountains and hills. Green often indicates vegetation or forested areas, while red is commonly used for man-made features like roads and boundaries. By using blue specifically for water, maps provide an immediate visual cue that enhances navigational accuracy and understanding of the terrain.
