The color of an object depends on the direction the object is seen from 
and on the rest of the scene, and the scene isn't fully constructed when 
the file is still being parsed. So no, you can't get the color that way. 
If you have the pigment, you can evaluate its color instead, which is 
normally independent of viewing direction.

Another thing: generating a surface from a cloud of unconnected points 
is extremely difficult. It is actually impossible to do so perfectly, 
though simply using a large number of points can give good results in 
many cases. You would really be better off designing meshes for each 
component. This doesn't necessarily require a mesh editor, you could 
write code in POV that generates the meshes you need, as long as there 
aren't any difficult differences or intersections.
