How to choose colour ramp to use for elevation?
1) has all the highest peaks just below 1500m while the German Alps rise above 2900m. Making a limit in the color ramp at 1500 visually separates these two topographic areas. See how in first example the alps are more distinct from the rest (probably not so easy to see in this small scale).
What kind of color ramp does Eduard Imhof use?

How is the color ramp chosen in ArcGIS?
This algorithm takes the shortest path through the color spectrum. If you think of the color spectrum as a wheel of color progression beginning and ending with red, colors are chosen along the shortest distance on the circumference of the wheel to create the color ramp.
Which is the best rendering technique for elevation?
For example a common rendering technique is to use deep greens for the valley bottoms, progressively lighten as one travels upslope, moving through browns and creams, to arrive finally on whites or pale blue/purple at the mountain peaks. (The technique is called hyspometric or elevation tinting.)
