How many basic colors are there on a topographical map?

Topographical maps typically use five basic colors to represent different features of the terrain. Each color serves a specific purpose:

1. Green is generally used for areas of vegetation, such as forests and gardens.

2. Brown indicates elevation and contour lines, providing information on the terrain's shape and height.

3. Blue is used for water bodies like rivers, lakes, and ponds.

4. Red often marks populated areas, roads, and highways, giving insights into human infrastructure.

5. Yellow may be used for agricultural land or less densely populated areas.

These distinct colors help users quickly interpret features and understand the topography of a given area. The varied colors enhance the map’s usability and make it easier for users to relate the visual representation to the physical landscape.
