Hypsometric colors vary with the terrain's elevation and thereby
emphasize the third dimension. Areal thematic information can be
combined with shaded reliefs. Colors according to nature try to
illustrate the climate and natural vegetation. A yellow tone can
simulate an illuminated relief and thereby enhance the three-
dimensional appearance of a shading. Deriving beautifully
colored shaded relief is possible from single gray-scale
shading. Based on a cartographer's artistic preference, colors
can vividly depict the third dimension of terrain.
