Question

why do cartographer use colour in maps? List at least four colours used in map-making and the geographical feature they represent.​

Answer 1

Map coloring is the act of assigning different colors to different features on a map. There are two very different uses of this term. The first is in cartography, choosing colors as a form of map symbol to be used on a map. The second is in mathematics, where the problem is to determine the minimum number of colors needed to color a map so that no two adjacent features have the same color.

Carefully choosing colors ensures that the map is intuitive and easy to read. This process is referred to as feature association. Also, the cartographer must take into account that many people have impaired color vision, and colors must be used that are easily distinguishable by such readers.
