I thought I'd twigged an answer, but only found that the Surface Color confounds your aim. GLSL code needs to be able to allow for the Spline objects colour settings to be rendered and included in the resulting final render. Almost all attempts at this end, once I'd figured that I'd misled myself earlier, failed to resolve the issue.
varying vec4 Color;
void main (void)
{
gl_FragColor = Color * gl_Color;
}
this change to the fragment shader should move you closer, include some of the toneburst Color shader stuff within tb_VTF_vBomb_0.5.qtz to be found elsewhere upon this site and you should be making real leaps forward.
for instance the addition of the following into the vertex shader after the gl_Position would also help no end.

Should also have emntioned the Lighthouse tutorials http://www.lighthouse3d.com/tutorials/glsl-tutorial/color-shader/ - good GLSL exemplar / tutorial set.
Thanks so much, cybero. I was looking at toneburst's vBomb but couldn't put the answer together.
The answer was found on Lighthouse's tutorial, whilst toneburst's GLSL example was also exploiting the Model Projection Matrix.
Excellent! Thanks again for looking into it.
