I'm not Mr. Math. M. Attika, and I'll probably never be, so have some mercy: For contour plots and 3D sections, I've been trying for a while now to get a grip on the coloring. The functions I want to display can take positive and negative values, and I would like to display these in "topographical colors", ie, deep blue for large negative values, up to dark brown and white for large positive ones. But I simply do not know how. I end up with this "Hue[]" function which gives me a rather silly rainbow arangement. Any hints of you specialists?
