Where sh is the height scaled to lie between 0 and 1. You can define cf any way you like, so long as cf[sh] is a color directive for all values of h between 0 and 1. Example: ListPlot[..., ColorFunction -> (Hue[.8(1-#)]&) ] will color from purple (lowest) to red (heighest). Incidentally, the brackets round Hue[.8(1-#)]& are essential to stop, without them Mathematica takes ColorFunction -> (Hue[.8(1-#)]&) to be (ColorFunction -> Hue[.8(1-#)])&, which is not an option.

If I just use "Hue", the high and low values are red. I've got a lot of contours, so I want to avoid having to define a color individually for each one. I'm running Mathematica on a Windows machine.
