What does red represent on a map?

On a map, red typically signifies major roads or highways. This use of color is standard in cartography, where vibrant colors like red draw the eye and convey important information about transportation routes. Major roads are crucial for navigation, connecting cities, towns, and regions, and using red for them helps users quickly identify their paths on the map.

In contrast, other colors might represent different features: blue often indicates water bodies, green can depict parks or forests, and brown may signify elevation changes, such as hills or mountainous areas. Military zones are usually represented with specific symbols or shades distinct from red, ensuring there is clarity in differentiating various types of land use or structural elements on a map. Understanding these color codes is essential for effective map reading and navigation.
