Use ColorFunction. I give you two examples just to illustrate what happens. Tom Wickham-Jones's book Mathematica Graphics is a splendid reference. In[1]:= ListDensityPlot[ Table[x y, {x, 0, 2 [Pi, Pi/8}, {y, 0, 2 Pi, Pi/8}], ColorFunction -> Hue]; In[2]:= ListDensityPlot[ Table[x y, {x, 0, 2 Pi, Pi/8}, {y, 0, 2 Pi, Pi/8}], ColorFunction -> (If[# < 0.5, RGBColor[0, 2#, 0], RGBColor[2 (# - 0.5), 0, 0]] &)]; Tomas Garza Mexico City Fabio Cavaliere wrote: > Hi.
