Greetings, I would like to create a ListDensityPlot in which the color is "deep" blue for function values of -10 and "deep" red for function values of +10, and varies linearly for function values in between -10 and +10. (I'm plotting the electric potential on a surface of points (x,y); the voltage ranges from -10 V to +10 V.) Is there a way that I can create such a ColorFunction for use in several ListDensityPlot plots? Thank you so very much for your time! Andrew DeYoung Carnegie Mellon University
