hello,
i've a function wich i plot the contourplot:

In > disp[kl_, z_] :=
SetPrecision[
1 + (1/kl)^2*(1 +
I*Sqrt[Pi]*(z/(Sqrt[2.]*kl))*
Exp[-(z/(Sqrt[2.]*kl))^2]*(1 + Erf[I*z/(Sqrt[2.] *kl)])), 100];


In > ContourPlot[Abs[disp[0.1, x + I y]]^2, {x, -1.5, -.5}, {y, -0.5, 0.5},
ColorFunction -> "IslandColors",
Contours -> ({4, 1, 0.4, 0.25, 0.15, 0.05, 0.01, 0.001} // Reverse)]



ok it works, but if i want to make another type of coloration:

ColorFunction-> RGBColor[0,0,#]& it doesn't work: i've the error message:

ContourPlot::nonopt: "Options expected (instead of
ColorFunction->RGBColor[0,0,#1]&) beyond position 3 in
ContourPlot[Abs[disp$196[0.1,x+\[ImaginaryI]\y]]^2,{x,First[{-1.5,1.5}\
],Last[{-1.5,1.5}]},<<3>>,PlotPoints->10]. An option must be a rule
or a list of rules. "


the documentation isn't very explicit...
it say that the argument of the color function must be the contours..... i dont understand why RGBColor[0,0,#]& doesn't work....

thanks for help
