[Tex/LaTex] Beamercolorbox has no color

beamer

I'm using the Warsaw beamer theme and try to customize it because the section headline is way too big for my presentation (about 7 sections). I found a way to display only the section names in the headline.
It looks pretty much like I want it to except the headline is not colored. The highlighting of the sections works but the colors won't. I'm not quite sure what the problem is. I use a beamercolorbox but it's just white. In the footline the exact same code produces a colored box.

The code I use for the headline:

\setbeamertemplate{headline}
{%
\begin{beamercolorbox}[wd=\paperwidth,ht=5ex,dp=3.5ex]{sec}%
    \raggedright%
    \hspace*{2em}%
    {\insertsectionnavigationhorizontal{0.7\textwidth}{}{}}%
\end{beamercolorbox}%
}

I'd really appreciate your help,

You have to setup the color used for the headline template

\setbeamercolor{headline}{fg=yellow,bg=red}

should draw your box with a red background and a yellow text.

[Tex/LaTex] Multilinetext in beamercolorbox

In places, where multi-line text doesn't work, you could try \parbox.

Also here it works with \\ if you would put the contents into a parbox. Alternatively, you could use \newline instead of \\. However, if you use \\ inside the parbox, you could specify optional spacing, such as \\[2pt].

Another approach is using a simple table in that box in the header, with adjusted \arraystretch value if desired, such as by

\begin{tabular}{@{}r@{}}

In all cases, increase the height of the beamercolorbox, this means the parameter ht in the argument of the beamercolorbox environment.

[Tex/LaTex] Customize mini frame navigation

As said in the comments, the right way to proceed is to define separately the two templates headline and frametitle.

Here is a possible implementation (as test image I used the logo of my university):

\documentclass{beamer}
\usepackage{lmodern}
%=====================================================================
% Color definition

% Setzt Deep Harlequin (dunkler)  
\definecolor{jvagreen}{RGB}{22, 89, 0}

% Setzt Vivid Gold (dunkler)
\definecolor{jvagold}{RGB}{231, 202, 0}

% Farbe der Elemente der headline
\setbeamercolor{section in head/foot}{fg = jvagold, bg = jvagreen}

%=====================================================================
% Templates - headline, frametitle

\makeatletter
% Komprimiert die miniframe Kreise auf eine Linie
\beamer@compresstrue
\makeatother

% Definiert die headline
\setbeamertemplate{headline}
{ 
\includegraphics[width=0.15\paperwidth]{logopolito} % test logo
\begin{beamercolorbox}[wd=.85\paperwidth,right]{section in head/foot}
    \rule{0.85\paperwidth}{1pt}
    %Vertikaler Abstand
    \vskip10pt
    %Fügt die Standard-Navi ein (miniframes)
    \insertnavigation{0.85\paperwidth}
    \vskip8pt
    \rule{0.85\paperwidth}{0.5pt}
    \vskip27.5pt % same height of the example provided, but IMHO is too much
    \rule{0.85\paperwidth}{1pt}
\end{beamercolorbox} 
}

% definition of the frametitle
\setbeamertemplate{frametitle}
{
\vskip-24pt % to shift up the frametitle
\hbox{ 
 \begin{beamercolorbox}[wd=.0675\textwidth]{} % left shift
 \end{beamercolorbox} 
 \begin{beamercolorbox}[sep=4pt]{section in head/foot}
 \insertframetitle
 \end{beamercolorbox} 
 }
}

\begin{document}
\section{Test 1}
\subsection{first}
\begin{frame}{A title}
hello
\end{frame}

\subsection{second}
\begin{frame}{A second title}
hello
\end{frame}

\section{Test 2}
\subsection{first}
\begin{frame}{Another title}
hello
\end{frame}

\subsection{second}
\begin{frame}{A second title}
hello
\end{frame}

\section{Test 3}
\subsection{first}
\begin{frame}{Last title}
hello
\end{frame}

\subsection{second}
\begin{frame}{A second title}
hello
\end{frame}

\subsection{second}
\begin{frame}{A third title}
hello
\end{frame}
\end{document}

The final result is:
