und die Frage ist, wie man das Design ändert, um die beiden oberen Zeilen in der gleichen Farbe zu erhalten, die unten verwendet wird, also die erste in Lachsfarben und die zweite in IndianRed2.

Antwort1

Stellen Sie die beiden Farben ein (ich gehe davon aus, dass die verwendeten Farbnamen in Ihrem System verfügbar sind):

\setbeamercolor{top}{bg=salmon}
\setbeamercolor{bottom}{bg=IndianRed2}%

und ändern Sie dann die Definition der Überschriftenvorlage in

\setbeamertemplate{headline}
{%
  \begin{beamercolorbox}[colsep=1.5pt]{upper separation line head}
  \end{beamercolorbox}
  \begin{beamercolorbox}[ht=1.7ex,dp=1.125ex,%
      leftskip=.3cm,rightskip=.3cm plus1fil]{top}
    \vskip2pt\insertsectionnavigationhorizontal{\paperwidth}{}{}
  \end{beamercolorbox}%
  \ifbeamer@theme@subsection%
    \begin{beamercolorbox}[colsep=1.5pt]{middle separation line head}
    \end{beamercolorbox}
    \begin{beamercolorbox}[ht=1.7ex,dp=1.125ex,%
      leftskip=.3cm,rightskip=.3cm plus1fil]{bottom}
      \usebeamerfont{subsection in head/foot}\insertsubsectionhead
    \end{beamercolorbox}%
  \fi%
  \begin{beamercolorbox}[colsep=1.5pt]{lower separation line head}
  \end{beamercolorbox}
}
