我正在考虑使用 fancyhdr 包来完成这项任务，根据这个问题，但我还不具备完成它所需的知识。
我正在使用以下代码：
\documentclass[a4paper,12pt,twoside,openright]{memoir}
\usepackage[utf8]{inputenc} % If utf8 encoding
\usepackage{librecaslon}
\usepackage[T1]{fontenc}
\usepackage[english]{babel}
\usepackage[final]{microtype}
\usepackage{fetamont}
\usepackage{graphicx} % Include figures
\usepackage{lmodern}
\usepackage{titlesec}
\usepackage{xcolor}
\usepackage{alphalph,etoolbox}
\usepackage{fancyhdr}

\frontmatter
\mainmatter
% \pagestyle{style1}
\chapter{How to build a time machine}
\lipsum[1-12]
% \pagestyle{style2}
\chapter{How to destroy a time machine}
\lipsum[1-12]
% \pagestyle{style1}
\chapter{How to build a time machine}
\lipsum[1-12]
\backmatter
\end{document}
我需要改变的是位于之间的代码页眉和页脚和文件。
代码当前在每个奇数页的页眉内创建彩色框，并且每个页面都这样做。我的目标是创建一个没有这些框的页眉样式，同时在第二个页眉样式中保留当前样式，我正在考虑实现以下代码以完成此操作：
\fancypagestyle{style1}{ % without colored boxes
}
\fancypagestyle{style2}{ % with colored boxes
}
我需要两个标题完全相同，除了一个标题没有那些框而另一个标题有那些框之外。
