# How to change the custom color of the theme “Frankfurt”?

I am making some slides for a presentation, using the Winedt and using the theme Frankfurt. Can anyone suggest, how to change the color of the slide from purple to dark blue, or some more professional color?

I got the following slide, while running the following code:

\usetheme{Frankfurt}
\setbeamercolor{structure}{bg=black, fg=sgibeet}
\beamertemplateshadingbackground{purple!0}{white}

The default color of the frame title background using the Frankfurt theme already is a (dark) blue:

\documentclass{beamer}
\usetheme{Frankfurt}
\begin{document}
\begin{frame}{Frame Title}
\end{frame}
\end{document}


In your document, you overwrote this color using \setbeamercolor{structure}{bg=black, fg=sgibeet}. To change the color from the purple (sigibeet in your case) you could use something like \setbeamercolor{structure}{fg=blue!50!black} that yould result in the following output:
