如何在 Beamer (Szeged) 中更改主题颜色和添加徽标

Question

我怎样才能改变我的演讲内容：

对此：

关于左下角的自定义主题颜色和徽标。

这是我目前的代码：

\documentclass[hyperref={pdfpagelabels=false}]{beamer}
\usepackage{lmodern}
\usetheme{Szeged}
\usetheme[compress]{Singapore}
\usepackage{textpos}

%Removes gradient color
\makeatletter
\AtBeginDocument{%
{
\usebeamercolor{section in head/foot}
}
\pgfdeclareverticalshading{beamer@headfade}{\paperwidth}
{%
color(0cm)=(structure.fg!0!bg);
color(1.25cm)=(structure.fg!0!bg)%
}
\setbeamercolor{section in head/foot}{bg=}
}
\addtoheadtemplate{\pgfuseshading{beamer@headfade}\vskip-1.25cm}{}
\makeatother

\begin{document}

\section{Section no.1} 
\begin{frame}
\frametitle{frame title} 
Each frame should have a title.
\end{frame}
\subsection{Subsection no.1.1  }

\end{document}

希望这不是重复的，但我无法在其他地方找到解决方案。
