I'm using classicthesis
and I'd like to change the formatting of the chapter title a little bit (f.e. size and color). I think I've found the according part in the classicthesis-style
% ********************************************************************
% layout of the chapter-, section-, subsection-, subsubsection-,
% paragraph and description-headings
% ********************************************************************
\RequirePackage{titlesec}
% chapters
\ifthenelse{\boolean{@linedheaders}}%
{% lines above and below, number right
\titleformat{\chapter}[display]%
{\relax}{\raggedleft{\color{halfgray}\chapterNumber\thechapter} \\ }{0pt}% change color to red
{\titlerule\vspace*{.9\baselineskip}\raggedright\spacedallcaps}[\normalsize\vspace*{.8\baselineskip}\titlerule]% change size to \huge
}{% something like Bringhurst
\titleformat{\chapter}[display]%
{\relax}{\mbox{}\oldmarginpar{\vspace*{-3\baselineskip}\color{halfgray}\chapterNumber\thechapter}}{0pt}%
{\raggedright\spacedallcaps}[\normalsize\vspace*{.8\baselineskip}\titlerule]%
}
but when I try to change color and size of the text, nothing happens.
\documentclass[twoside,openright,titlepage,numbers=noenddot,headinclude, footinclude=true,cleardoublepage=empty,abstractoff, BCOR=5mm,paper=a4,fontsize=11pt,ngerman,american]{scrreprt}
\input{classicthesis-config}
\usepackage{lipsum}
\begin{document}
\pagestyle{scrheadings}
\part{Introduction}
\chapter{First chapter}
\section{First section}
\lipsum[1-18]
\end{document}
scrreprt
andtitlesec
do not cooperate very well. Try to comment out\pagestyle{scrheadings}
Part I INTRODUCTION
or the header of the pages with new chapters? What you have added in your question is about chapters while the text is about the title format.
