I have a very simple question – there are a bunch of beamer themes, however, all of them have white background. I would like to use some theme, let's say Warsaw (since it is perfect), however I'm looking for some dark version of this theme.
The most important thing for me is black background – unfortunately projectors are not as good as screens/printed papers, so dark themes are much better for long presentations, etc.
Any suggestions? Ideally, I'd like to change just a line or so in the beginning of my tex file with presentation.
