What color on a map typically represents water?

On maps, water bodies such as lakes, rivers, and oceans are commonly represented by the color blue. This convention is widely recognized and is used in various types of maps, including topographic and nautical charts, to distinguish water areas clearly from land features. The use of blue helps map readers quickly identify and assess the presence of water in a given area, which can be important for navigation, geographic study, and planning. This understanding of color representation is essential for interpreting maps effectively in various contexts, including military operations, environmental assessments, and geographical education.
