Here is an example:
ParametricPlot3D[{u,v,u^2+v^2,Hue[Abs[u v]]},{u,-1,1},{v,-1,1},
Lighting->False];
The trick is to specify a 4-dimensional vector to plot, where the 4th
component is the colour function you want to use. This approach makes sense
if you regard colour as representing position along the 4th dimension.
