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]] &)];
