It will never work with ContourShading->True in both plots (the default behavior), and would be quite difficult to work around, since Mathematica doesn't have the notion of "transparent" colors. Implicit functions must be plotted with ImplicitPlot, defined in the Graphics`ImplicitPlot` package. John Fultz Wolfram Research, Inc.
