What maps use brown and green to show how many people us the land?

Topographic maps often use brown and green to depict elevation and land usage. Brown typically represents higher elevations, such as hills and mountains, while green indicates lower elevations, often representing vegetation and agricultural land. These color schemes help illustrate how different terrains are utilized by people, such as farmland versus undeveloped areas. Additionally, land use maps may also incorporate these colors to show various land uses and population density.
