I determine the colour of a ParametricPlot3D
graphic with a Directive RGBColor. The Option
Lighting->False is needed for the colour to
appear.

The problem is the sense of volume is kind of
lost, since EdgeForm[] Directive is also present.

I would like to be able to render graphics with
both specific colours and shading. A set of
different graphics with these Directives and Options
is presented together using the command Show.

Maybe the Options AmbientLight and Shading have
something to do with it.

I don't understand exactly what you are trying to do, but you should take a
look at  the Graphics Tricks available from my web site (URL below).  There
I explain and demonstrate most of the options and primitives that control
lighting and coloring in Mathematica.
