我想更改投影仪侧边栏的颜色，但我不知道\setbeamercolor{}{}侧边栏颜色需要哪个参数。我使用\usepackage{xcolor}并指定我自己的颜色，如下所示：\definecolor{myBlue}{RGB}{45,170,250}。
我的 tex 编译器是xelatex
这是我的 tex 文件：
\documentclass{beamer}
% beamer theme
\usetheme{Marburg}
% german spelling
\usepackage[english,ngerman]{babel}
% set font encoding
\usepackage[T1]{fontenc}
% math stuff
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
% color
\usepackage{xcolor}
% set font to Helvetica Light
\usepackage{xltxtra}
\setsansfont[Ligatures=TeX]{Helvetica Light}
\title{Präsentation}
\author{Max Mustermann}
\date{\today}
% removes navigation bar
\beamertemplatenavigationsymbolsempty
\begin{document}
\begin{frame}
\frametitle{Ein Demotitel}

答案1
如果您想知道beamer某个主题使用了哪些颜色，请查看其定义样式文件beamerthemeMarsburg.sty。您将在那里看到：
\mode<presentation>
\usecolortheme{whale}
\setbeamercolor*{titlelike}{use=structure,fg=structure.fg}
\useoutertheme[height=0pt]{sidebar}
\setbeamercolor{sidebar}{parent=palette primary}
{\usebeamercolor{palette quaternary}}
{\usebeamercolor{palette primary}}
\setbeamertemplate{sidebar canvas \beamer@sidebarside}[vertical shading][top=palette quaternary.bg,bottom=palette primary.bg]
这意味着该主题使用颜色主题whale，并且sidebar基于vertical shading颜色palette quaternary.bg和palette primary.bg。
现在你有两种选择，更改palette定义或仅更改sidebar定义。如果你想确保基于此颜色的每个模板也发生更改，则必须使用第一种。如果你只想更改侧边栏背景，只需添加
\definecolor{myBlue}{RGB}{45,170,250}
\makeatletter
\setbeamertemplate{sidebar canvas right}[vertical shading][top=palette quaternary.bg,bottom=myBlue]
\makeatother
在你的序言中。当然，如果你的侧边栏在左边，请right用进行更改left。结果如下：
完整代码如下：
\documentclass{beamer}
% beamer theme
\usetheme{Marburg}
% german spelling
\usepackage[english,ngerman]{babel}
% set font encoding
\usepackage[T1]{fontenc}
% math stuff
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
% color
%\usepackage{xcolor}
% set font to Helvetica Light
\usepackage{xltxtra}
\setsansfont[Ligatures=TeX]{Tahoma}

笔记：
- 我使用 Tahoma 字体而不是原始的 Helvetica Light。
