Names color collides with buildings color about opentopomap

I can see the problem, but brown may not be the best solution. After a look at some examples from the ATKIS, I would recommend using a light grey for the polygon fillings and a little darker for the borders.

I would like to see some examples of that two approaches to compare.

This was worst on zoom 14, because buildings are rendered completely black. On zoom 13 and 15 the texts are quite readable.
I changed the halo to 2 pixels with a opacity of 0.8. You will see the results, when we switch back to our main server in a few days.

Thank you for your bug report!

This would be perfect:

With Mapnik 3.0 there will be the option to do halo-comp-op. This will be the solution. :-)

The problem of halo-comp-op is that it gets executed to the whole layers drawn before. Right now there is no way to define layer groups in order to execute the comp-op to a defined group. See mapnik/mapnik#2267 and https://github.com/mapnik/mapnik/wiki/Compositing
