I have adjusted the style files for the metropolis beamer style by adjusting the beamercolorthememetropolis.sty file and placed the new file inside the main folder of my project.

If I then run the following MWE everything goes fine:

documentclass{beamer}



usetheme{metropolis}



begin{document}



begin{frame}{test} test end{frame}



end{document}

My problem is that this clutters my file management and that I would rather have the new beamercolorthememetropolis.sty file in a subfolder. My attempt was:

documentclass{beamer}



usetheme{metropolis}



usepackage{./Preliminaries/beamercolorthememetropolis}



begin{document}



begin{frame}[fragile]{titel} test end{frame}



end{document}

But this spits out various errors e.g.:

LaTeX Warning: You have requested package `./Preliminaries/beamercolorthememetr opolis',

               but the package provides `beamercolorthememetropolis'.



Package: beamercolorthememetropolis 2015/12/04 Metropolis color theme ) (./Preliminaries/beamerinnerthememetropolis.sty

                                                   l.49 }

       Your command was ignored. Type  I <command> <return> to replace it with another command, or  <return>  to continue without it.

It would appear that my usepackage fails to overwrite some settings that are present in the stock version of metropolis if I include them in this fashion...

You cannot modify a latex sty file and keep the same name as this violates LPPL licence.

I see a few alternatives

• 
  

  use the original metropolis theme and make the changes locally in in your beamer document. For example if you want to change some colour:

  
  
  

  documentclass{beamer}
  
  
  
  usetheme{metropolis}
  
  
  
  setbeamercolor{frametitle}{fg=red, bg=blue}
  
  
  
  begin{document}
  
  begin{frame}
  
  frametitle{test}
  
  end{frame}
  
  end{document} 
  
  

  
  



• if the changes are too numerous and clutter you document, you can outsource the changes into a new file, say ./preliminaries/changes.tex and input{./preliminaries/changes.tex} it into your document




• Or make a copy of the whole beamertheme-metropolis folder, rename all files therein which you want to change (remember to also change the package name and the names of the loaded sub-themes in what originally has been called beamerthememetropolis.sty). If you prefer to have this new theme in a subfolder, you can adjust the paths to load the theme from a subfolder.
