What color on a map classifies man-made features?

The classification of man-made features on a map is indicated by the color red. This is important for understanding cartographic conventions, as red typically represents cultural or constructed elements like roads, buildings, and other infrastructure. These features are essential for navigation and planning, making it critical for map readers to easily identify them.

In contrast, other colors denote different elements: blue usually represents water features, such as rivers, lakes, and oceans; green signifies natural vegetation or forested areas; and black is often utilized for terrain features like elevation or unpaved roads. Recognizing these conventions is important for effective map reading and ensures that users can interpret the information presented accurately.
