The following code allows one to manipulate the parameters and see the corresponding contours for a bivariate normal. What I would like to do is make the background white after the density is below a value say .02. Using the following code creates a dark blue background. I was wondering if is blue because the density is less a particular value but am not sure. Is this possible to specify a density value, below which you can specify a color? I played around with ContourShading but with no success. Here is my code:
Manipulate[
ContourPlot[
PDF[BinormalDistribution[{Subscript[\[Mu], 1], Subscript[\[Mu],
2]}, {Subscript[\[Sigma], 1], Subscript[\[Sigma],
2]}, \[Rho]], {x, y}], {x, -3, 3}, {y, -3, 3},
ContourLabels -> True, PlotRange -> All,
PlotPoints -> 40], {Subscript[\[Mu], 1], -2, 2}, {Subscript[\[Mu],
2], -2, 2}, {Subscript[\[Sigma], 1], 1, 3}, {Subscript[\[Sigma], 2],
1, 3}, {\[Rho], -0.9, 0.9}]
