An easy way to describe a color in Mathematica is to use Hue[col]
where col is a number between 0 and 1.
Hue[0] and Hue[1] are both red and the values in between describe all
the other colors.
Now if you want to color a parametric surface use the following:
ParametricPlot3D[{f[u,v],g[u,v],h[u,v],Hue[c[u,v]]},{u,u0,u1},{v,v0,v1},opts___]
where c[u,v] is a function of u,v that returns a value between 0 and
1.
