Above is an illustration of a hypsometric map which shows detailed elevation of a region through contour and sometimes shading.  It is responsible for showing relief of the Earth's surface and different colors represent different levels.  In the picture above the lower elevations are green while the higher ones are depicted in browns and reds.
