What are the five colors on a map and what do they represent?

The correct answer highlights the conventional color scheme used on topographic maps to convey various features of the terrain.

Black is used to depict manmade objects, which can include buildings, roads, and other structures. This enables map users to easily identify urban areas and infrastructure.

Brown represents landforms, particularly contour lines that show elevation changes. This is critical for understanding the terrain’s relief and can help in navigation and planning.

Green indicates areas of vegetation. This can include forests, fields, and other types of plant cover. Recognizing vegetation is essential for a variety of military operations, as it affects visibility and movement.

Red is designated for primary roads, which are vital for understanding transportation networks. Identifying these roads can influence tactical decisions regarding movement and supply routes.

Finally, blue represents bodies of water, such as rivers, lakes, and streams. Water sources are crucial for logistics and can also affect strategic maneuvers during operations.

This standardized color code is essential for efficient map reading, allowing Marines to interpret map data effectively in a combat or training environment.
