Which color on a map is used to identify elevation and relief features, including mountain ranges?

The color brown on a map is used specifically to indicate elevation and relief features, such as mountain ranges and hills. This is achieved through contour lines that represent different elevation levels. The contours help visualizers understand the shape and steepness of the land by indicating how high or low various areas are in relation to sea level. By using brown for these features, maps provide users with an intuitive understanding of terrain and topography, aiding in navigation and geographic comprehension. Understanding this color scheme is crucial for anyone using topographic maps for outdoor activities, planning, and other applications that require knowledge of landforms.
