1. You need to use ContourPlot vice Contour
2. A function of a single variable does not generate much of a contour, but
in any event you need to specify a range in two dimensions
3. RGBColor has arguments, i.e., RGBColor[red, green, blue]
ContourPlot[Sin[x],{x,-Pi,Pi}, {y, -Pi, Pi},
ColorFunction->(RGBColor[#, 0, (1-#)]&)];
ContourPlot[Sin[x*y],{x,-Pi,Pi}, {y, -Pi, Pi},
ColorFunction->(RGBColor[#, 0, (1-#)]&)];
