a .4 contribution. A SpecularPower of 100 will give very small
highlights of the Specular color.

A description of this type of shading is given here:
http://en.wikipedia.org/wiki/Phong_shading

In summary, your picture corresponds to your property settings.

Since the bone is represented by a single isosurface, that surface can
only have "one color".

I suggest you study the wikipedia article and experiment by varying
each parameter individually.
