我想用 Beamer 制作演示文稿。我使用AAU侧边栏主题。
我想使用我自己定义的盒子\newt颜色框。但是，我无法修改标题的背景颜色（返回标题）以及文本的颜色（上下文）。或许其他属性是错误的。
MVE 是：
\documentclass[9pt]{beamer}
\usetheme[shownavsym, left]{AAUsidebar}
% If you want to change the colors of the various elements in the theme, edit and uncomment the following lines
\definecolor{mygreen}{cmyk}{0.82,0.11,1,0.25}
\setbeamertemplate{blocks}[rounded][shadow=true]
\setbeamercolor{itemize item}{fg=orange!20!black}
\setbeamertemplate{itemize item}[ball]
\setbeamertemplate{itemize subitem}[triangle]
\usepackage[utf8]{inputenc}
\usepackage[french]{babel}
\usepackage[T1]{fontenc}
\usepackage[many]{tcolorbox}
\newtcolorbox{MyBox}[1][]{

\begin{document}

我的代码有什么错误？
答案1
你的代码是正确的，除了两个小错误。第一个是你声明了mybox一个可选参数
\newtcolorbox{MyBox}[1][]{
默认情况下为空。您对的调用将\begin{MyBox}{Title}标题留空，并考虑Title部分文本。如果您使用，\begin{MyBox}[Title]标题将被视为这样并按预期打印。
第二个是忘记为beamer声明自己的颜色enumerate，因此，当您在框中coltext包含环境时，它会被覆盖。普通文本是用颜色书写的，但 或中的文本不是。enumeratecoltextenumerateitemizedescription
如果要更改enumerate所有文档中的所有颜色文本，请添加
\setbeamercolor{itemize/enumerate body}{fg=mygreen!50}
在您的序言中。但是，如果您只想将其应用到中MyBox，请将其插入到声明before upper=中\MyBox。此命令将更改正文的排版方式，但对于数字或项目，您必须重新定义enumerate item或itemize item模板。
