[Tex/LaTex] How to customize chapter heading style

chapterssectioning

I have customized the default chapter style like below. The chapter number font is Garamond number font, whereas the main text is Times font.

enter image description here

The codes:

\documentclass[a4paper, 12pt]{book}
\usepackage[T1]{fontenc}
\usepackage{newtxtext, newtxmath}
\usepackage{color}
\definecolor{RoyalRed}{RGB}{157,16, 45}
\renewcommand{\sfdefault}{mdugm} %Garamond
\usepackage[ ]{titlesec}  %
\titleformat{\chapter}[display]
  { \normalsize \huge  \color{black}}
  {\flushright \normalsize \color{RoyalRed} \MakeUppercase { \chaptertitlename } \hspace{1 ex} { \fontsize{60}{60}\selectfont \color{RoyalRed} \sffamily  \thechapter }} {10 pt}{\huge}  
  \begin{document}

\chapter{Introduction}
...
bla bla
...
\chapter{State of the art}
...
bla bla
...
\end{document}

So how to set the chapter title state of art as bold font?

Best Answer

Use {\bfseries\huge} at the end:

\titleformat{\chapter}[display]
  { \normalsize \huge  \color{black}}
  {\flushright \normalsize \color{RoyalRed} \MakeUppercase { \chaptertitlename \hspace{1 ex} }  { \fontsize{60}{60}\selectfont \color{RoyalRed} \sffamily  \thechapter }} {10 pt}{\bfseries\huge}

Code:

\documentclass[a4paper, 12pt]{book}
\usepackage[T1]{fontenc}
\usepackage{newtxtext, newtxmath}
\usepackage{color}
\definecolor{RoyalRed}{RGB}{157,16, 45}
\usepackage{titlesec}
\titleformat{\chapter}[display]
  {\normalsize \huge  \color{black}}%
  {\flushright\normalsize \color{RoyalRed}%
   \MakeUppercase{\chaptertitlename}\hspace{1ex}%
   {\fontfamily{mdugm}\fontsize{60}{60}\selectfont\thechapter}}%
  {10 pt}%
  {\bfseries\huge}%

\begin{document}

\chapter{Introduction}
...
bla bla
...
\chapter{State of the art}
...
bla bla
...
\end{document}
