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!
