[Tex/LaTex] Section and subsection colors using titlesec

colorsectioningtitlesec

Im trying to alter the colors on my section, subsection and subsubsection.

I do so using the titlesec page:

\titleformat*{\section}{\Large\bfseries\sffamily\color{red}}
\titleformat*{\subsection}{\large\bfseries\sffamily\color{red}}

But the problem is i have to enter the font and font size also. I am using the fontenc package:

\usepackage[T1]{fontenc}

But i cant seem to find out what font and size is being used for the section, subsection and subsubsection.

These 2 values i mean: \Large\bfseries\sffamily

I tried to look in the .sty but that wasent very helpful.

The second argument of the \titleformat*{\<name>}{<code>} is stored in a macro called \ttlf@<name> which (default) definition can be printed to the command line with \show\ttlf@<name>, after a \makeatletter of course.

\makeatletter
\show\ttlf@section

\ttlf@section:
macro:->\ttlh@hang {\normalfont \Large \bfseries }{\@seccntformat {section}}{\z
@ }{\ttl@passexplicit }{}. 

\show\ttlf@subsection

\ttlf@subsection:
macro:->\ttlh@hang {\normalfont \large \bfseries }{\@seccntformat {subsection}}
{\z@ }{\ttl@passexplicit }{}. 

\show\ttlf@subsubsection    

\ttlf@subsubsection:
macro:->\ttlh@hang {\normalfont \normalsize \bfseries }{\@seccntformat {subsubs
ection}}{\z@ }{\ttl@passexplicit }{}.

Therefore the correct settings for the requested title formats are:

\titleformat*{\section}{\normalfont\Large\bfseries\color{red}}
\titleformat*{\subsection}{\normalfont\large\bfseries\color{red}}
\titleformat*{\subsubsection}{\normalfont\normalsize\bfseries\color{red}}

Just for completeness here also the settings for \paragraph and \subparagraph:

\titleformat*{\paragraph}{\normalfont\normalsize\bfseries\color{red}}
\titleformat*{\subparagraph}{\normalfont\normalsize\bfseries\color{red}}
