Jean,
You can use the 4th color directive argument in the parametrization with
ParametricPlot3D. Here is an example.
ParametricPlot3D[{Cos[t]Cos[p], Sin[t]Cos[p], Sin[p],
Hue[(1 + Cos[t]Cos[p])/2]}, {p, -Pi/2, Pi/2}, {t, 0, 2Pi},
PlotPoints -> {20, 40},
Lighting -> False,
ImageSize -> 450];
If you wish, I can show you how to make a nice contour plot with smooth
edges on a sphere or other surface.

I want plot and color a surface x=f(u,v), y=g(u,v), z=h(u,v)
How to create a color function colorfunc[x,y,z] (or colorfunc[u,v])
that associate a color at each point of the surface ??
Thanks
Scuse for my very bad english language !!
