Hello Everyone:
I have a question regarding contour plots and color functions. I have a function of 2 variable, z = f(x,y) and I want to color the plane using 2 colors only, say Blue and Brown based upon some threshold value for f[x,y]. For example, if z < 1 , then color those regions brown otherwise color the regions blue. I tried (among many other failed attempts)
ContourPlot[f[x,y], {x, xMin, xMax}, {y, yMin, yMax}, ColorFunction -> cfun]
where
cfun[z_] := Which[z < 1, Hue[.63], z >= 1, Hue[.63]]
This colors the entire plane blue. Any suggestions would be greatly appreciated. Thanks.
