beamercolornavigation

How can I change the color of the navigation bar in beamer? I am using "Goettingen" theme. I tried several changes, but that did not work…

CODE:

\documentclass{beamer}

\usepackage[british]{babel}
\usepackage{graphicx,hyperref,url}
\usepackage{color}
\usetheme[left]{Goettingen}

\begin{document}

\begin{frame}
  \frametitle{Outline}

  \tableofcontents
\end{frame}

\section{Introduction}

  \begin{itemize}
    \item This is just a short example
    \item The comments in the \LaTeX\ file are most important
    \item This is just the result after running pdflatex
  \end{itemize}

    This style uses the following default styles:
    \begin{itemize}
      \item split
      \item whale
      \item rounded
      \item orchid

I am unsure which colors of the different navigation components you want to change, so let me go through some of them.

  • The color of the navigation symbols can be changed using:

    \setbeamercolor{navigation symbols}{fg=red, bg=green}

  • The color of the navigation panel you can change by putting 

    \setbeamercolor{structure}{fg=red}

    before \usetheme[left]{Goettingen}. Notice, however, that the colour will still be washed out, fading from top to bottom.

  • You can change the color of the titles in the navigation bar using

    \setbeamercolor{palette sidebar secondary}{fg=yellow,bg=blue}
\setbeamercolor{section in sidebar shaded}{fg=red,bg=black}

    The secondary colors are the ones currently active.

I am not advocating these particular choices, especially since this is what they do:

Here is the code that produced this image:

\documentclass{beamer}

\usepackage[british]{babel}
\usepackage{graphicx,hyperref,url}
\usepackage{color}
\setbeamercolor{structure}{fg=red}
\usetheme[left]{Goettingen}

\setbeamercolor{navigation symbols}{fg=red, bg=green}

\setbeamercolor{palette sidebar secondary}{fg=yellow,bg=blue}
\setbeamercolor{section in sidebar shaded}{fg=red,bg=black}

\begin{document}

  \begin{frame}{Outline}\tableofcontents \end{frame}

  \section{Introduction}\begin{frame}{Introduction}\end{frame}

  \section{Background}\begin{frame}{Background}\end{frame}
\end{document}

Finally, it is possible to have more than one color in the side bar by placing

\makeatletter
\setbeamertemplate{sidebar canvas \beamer@sidebarside}%
                  [vertical shading][top=green,bottom=blue]
\makeatother

after you have set the color them. Splicing this into the MWE above yields:

Again, pretty as they may be, I don't recommend any of these colors.
