   Perhaps people has a reason to ask for it... :)

  No, the "color Blue" statement is not on that sphere... it is on the
sphere inside the difference declared as "hollebollegijs", which indeed
is never used on the scene: look again at your own code...

  Look, bollen-1.pov still has the light at <0.0,0.0,-10000.0>, while the
camera is at <0.0,0.0,20.0>, and the sphere is <0,0,2>, so logically you
can only see the unlighted side of the sphere against the white
background.

   On bollen-01.pov you changed the background to black, and the light
position to <0.0,0.0,10000.0>, so now you are lighting the visible side
of the sphere, tough the light is very faint and distant, so it's
dark... again logical with respect to your scene setup.

   I don't see how that would be constructive at all... it would help you
getting this done, but nothing more. You will learn nothing, because you
will not see in other's code what you are not seeing on your own code.
The most constructive thing for you will be to follow the "beginning
tutorial" on the docs, because then you could easily figure out the
solutions to all of your current problems, or at least understand the
explanations offered by others.
