I slightly disagree here. In many cases, in color-coded surface plots, you do
not want to attribute the colors to, let's say, altitudes, but rather use the
color transitions as contour lines without explicitly drawing contours. You
could also use continuous colors, but it is amazing how this fails, while
something like 25 colors looks good.
