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.
