```Hi,

Needs["Graphics`ImplicitPlot`"];
f1 := x^2 + y^2 == 2;
f2 := x^2 + y^2 == 1;
plt = ImplicitPlot[{f1, f2}, {x, -3, 3}, AxesLabel -> {"x", "y"},
PlotStyle -> {{}, Dashing[{0.02}]}];

plt /. {{Line[pnts_]} :> {{RGBColor[1, 0, 0], Polygon[pnts]},
Line[pnts]}, {Dashing[dd_],
Line[pnts_]} :> {{RGBColor[1, 1, 1], Polygon[pnts]},
{Dashing[dd],
Line[pnts]}}} // Show

Regards
Jens
