您能帮我将演示文稿的标题“标题 ABC”插入到 LightCyan 颜色框中吗？
下面我附上我使用的代码：
\documentclass{beamer}
\mode<presentation>{
\usetheme{Madrid}
%\usetheme[secheader]{Boadilla}
\usecolortheme{dolphin}
}
%\usepackage[utf8]{inputenc}
%\usepackage{default}
\usepackage[english]{babel}
\usepackage[style=apa,backend=biber, natbib]{biblatex}
\DeclareLanguageMapping{english}{english-apa}
\DefineBibliographyStrings{english}{%
andothers = {et al.},
}
\usepackage{pgfplots}
\pgfplotsset{/pgf/number format/use comma,compat=newest}
\usepackage{amsmath,amsfonts,amssymb,bm}
\usepackage{multirow}
\usepackage{graphicx}
\usepackage{booktabs}
\usepackage{hyperref}
\usepackage{tikz}
\usepackage{makecell}
\usepackage[para,online,flushleft]{threeparttable}\usepackage{breqn}
\usepackage{adjustbox}
%\usepackage{color}
\usepackage{tabularx}
\usepackage{color, colortbl}
\definecolor{LightCyan}{rgb}{0.88,1,1}
\usepackage{booktabs}
\usepackage{color, colortbl}
\definecolor{Gray}{gray}{0.9}
%\usepackage[colorlinks=true,citecolor=blue]{hyperref}
\hypersetup{colorlinks=true,citecolor=blue, linkcolor=white}
\newcommand{\MYhref}[3][blue]{\href{#2}{\color{#1}{#3}}}%
\title[Mock Presentation, UC3M]{Title ABC}
\author[ABC] { ABC \\}
\institute[AUMM]{XYZ \\ }
\date{October, 2019}
\begin{document}
\begin{frame}

借助\setbeamercolor{title}您可以实现以下结果：
\documentclass{beamer}
\usetheme{Madrid}
\usecolortheme{dolphin}
\definecolor{LightCyan}{rgb}{0.88,1,1}
\setbeamercolor{title}{bg=LightCyan}
\title[Mock Presentation, UC3M]{Title ABC}
\author[ABC]{ABC}
\institute[AUMM]{XYZ}
\date{October, 2019}
\begin{document}
\begin{frame}
\maketitle
\end{frame}
\end{document}
