How do I change the blue shawdow around the frametitle to a different color? Or rather even get rid of the shawdow

[Solution: I used the \setbeamercolor settings AFTER \begin{document}. Writing it before that solves the issue.]

  • Can you show us a small example that includes how you changed the colours? – user36296 Jul 26 '16 at 19:42

  • Normally the shadow colour is determined by the colour of the title bar and the background colour. So I guess you are using some non-standard way to change the colour to green. In order to help you it would be really useful to know what you are doing. – user36296 Jul 27 '16 at 0:01
  • Completing your code fragments to a compilable document I get the following output: i.stack.imgur.com/nLRnc.png I used Texlive2016 and pdflatex, xetex and luatex to compile. What are you using? Can you make your example complete, e.g. with \begin{document} etc.? – user36296 Jul 27 '16 at 8:37

With Warsaw you can modify the topshade colors.

\documentclass{beamer}%
\usetheme{Warsaw}
\setbeamercolor{frametitle right}{bg=cyan!90}
\setbeamercolor{structure}{fg=cyan!90}
\mode<presentation>
%\setbeamercolor{background canvas}{bg=yellow}
\definecolor{dgreen}{rgb}{0.,0.6,0.}
\makeatletter
\pgfdeclarehorizontalshading[frametitle.bg,frametitle right.bg]{beamer@frametitleshade}{\paperheight}{% Frametitle
    color(0pt)=(dgreen);
    color(\paperwidth)=(frametitle right.bg)}
\AtBeginDocument{
    \pgfdeclareverticalshading{beamer@topshade}{\paperwidth}{%
        color(4pt)=(blue);
        color(8pt)=(blue!50!bg)    
    }
}
\begin{document}

\section{A section}
\begin{frame}
  \frametitle{A section}
  \begin{itemize}
    \item Test test
    \begin{itemize}
        \item Test test
        \begin{itemize}
            \item Test test

        \end{itemize}
    \end{itemize}
  \end{itemize}

\end{frame}
\section{Another section}
\begin{frame}
  \frametitle{Another section}
  Yes!  Test test
\end{frame}
\section{Final section}
\begin{frame}
  \frametitle{Final section}
  No!  Test test
\end{frame}

\end{document}

  • This didn't work for me, using Frankfurt. Other appraches? I edited the question for more details. Thank you, though! – Ad. We Jul 27 '16 at 1:04
