The simple ColorFunction->Hue option in Plot3D, ContourPlot, and DensityPlot, makes z = 0 appear the same as z = 1 (i.e., both bright red), a situation which seems to me to make these plots confusing and more difficult to interpret, given that "high peaks" and "sea level valleys" may be the most interesting features of such a plot. Do others have any favorite, not too messy ColorFunctions that make values near z = 0 tend toward white, or grey, or less bright, or something so that there's a clearly unidirectional visual effect going from values of z near 0 to those near z = 1? [And as a side question, a simple Prolog or Epilog code to put one of those scaled and labelled vertical color bars alongside a ContourPlot or DensityPlot, perhaps with the same vertical height as the plot itself?]
