答案1

要将页眉中章节标题的背景颜色从黑色更改为蓝色，请添加\setbeamercolor*{section in head/foot}{bg=myblue, fg=white}和要将框架标题的背景颜色从蓝色更改为灰色，请\colorlet{titleleft}{myblue} \colorlet{titleright}{myblue}替换\colorlet{titleleft}{gray} \colorlet{titleright}{gray}。

正如 A Diyanat 已经解释的那样他们的答案，bg改变了背景颜色，fg改变了字体颜色。

答案2

要更改投影仪框架的前景色和背景色，可以使用以下几行：

\colorlet{titleleft}{gray!80}  %<----- left half of frame title background color
\colorlet{titleright}{gray!60} %<----- right half of frame title background color
\setbeamercolor*{frametitle}{fg=white} %<---- Color of the frame title text

对于更改左框架标题，我们有：

\setbeamercolor{palette quaternary}{bg=Blue,fg=red}

值得注意的是，“fg”和“bg”分别表示前景色和背景色。总之，请考虑以下示例：

 \documentclass[xcolor=dvipsnames]{beamer}

\usetheme{Madrid}
\useoutertheme{shadow}

\makeatletter
\pgfdeclarehorizontalshading[titleleft,titleright]
{beamer@frametitleshade}
{\paperheight}{%
 color(0pt)=(titleleft);
color(\paperwidth)=(titleright)}
\makeatother

\colorlet{titleleft}{gray!80}
\colorlet{titleright}{gray!60}
\setbeamercolor*{frametitle}{fg=white}
\setbeamercolor{palette quaternary}{bg=Blue,fg=white}

\begin{document}
\section{Introduction}
\section{Positive linear relations}
\begin{frame}{Linear relations}
Example.
\end{frame}
\end{document}
