First of, thanks for your quick help!
In fact, the 'table to points' filter was the problem. I was misled by
the 'interpolate colors' option shown in the help (that I couldn't
find). I performed the 'table to structured grid' filter with the
extents filled in correctly (that was the problem when I tried this
filter on my own) and it delivered the result I expected!
Thanks again,
Sven
The table to structured grid filter only works if your csv file
actually represents a 2D or 3D array. If your points have no implied
topology, you can impose one by running the Delaunay 3D filter.

Someone else may come up with a better answer, but here goes.
What you are doing is reading in point data, and displaying this
point data in 3d space. You have not created a solid for ParaView
to color -- just points.
I believe what you want to do is actually create a solid. This can
be done using the "table to structured grid filter". Turns out
that I had this question from a user earlier today, and wrote up a
quick and dirty wiki page on it, located here:

*Subject:* [Paraview] No interpolation of colors possible
(table-to-points result)
Hi,
I'm quite new to Paraview and have an urgent problem. I employed
the help that was/is available to me - meaning
http://paraview.org/OnlineHelpCurrent/ - but couldn't solve the
problem until now. Actually, I don't consider my problem to be
really complicated, it might well be that the solution is one
mouse-click away.
APPROACH
--> a dataset (CSV-file) of a three dimensional tomography was
imported into Paraview
--> 'table to points'-filter was performed, using the x-,y- and
z-values (latter are negative) of my dataset (first three columns)
--> 'colour by...': the fourth data column with the resistivity
values was chosen
-|-> finally I wanted the colors to be interpolated between the
points.
PROBLEM: I can't perform the color interpolation.
In the wiki there's a small picture showing the color section with
the option 'color by...'. Above this dropdown-list you can see
'interpolate colors"
being activated.
http://paraview.org/OnlineHelpCurrent/Display.html
In my case, there is no such thing, instead the option ist named
'interpolate scalars'. In addition to that, in my display there's
a second (smaller and empty) dropdown-list next to 'color by...'
and an option called 'apply texture: none' (grey).
Many thanks in advance if you can help me! (unfortunately I can
only answer tomorrow and then not until next monday, 26th July)
