Text Formatting ⇒ footnote coloring

[tuttoweb]

Hello guys,
I'm a brandnew latex user and I dont have any clue how to put some color in footnotes. I'm not refering at the text itself, but I want to colorize the footnote's number.
In addition, footnotes have different numerations for different chapters. I would like ti keep the same numeration for the whole document.
Thank you very much in advance.

Hi,

welcome to the board!

• One way is to redefine the internal macro \@makefnmark using color.
• Regarding the counter, you could use the chngcntr package to customize it.

Here's a complete small example demonstrating both:

Code: Select all

\documentclass{book} 
\usepackage[svgnames]{xcolor}
\newcommand*{\footnotemarkcolor}{red}
\makeatletter
\renewcommand*{\@makefnmark}{\hbox{\@textsuperscript{%
  \color{\footnotemarkcolor}\normalfont\@thefnmark}}}
\makeatother
\usepackage{chngcntr}
\counterwithout{footnote}{chapter}
\begin{document}
\chapter{One}
Text\footnote{example}
\chapter{Two}
Text\footnote{second example}
\end{document}

thank you stefan. Everything is seems alright now, even though I didnt catch thoroughly the syntax. Could you possibly explain it please?

Code: Select all

\usepackage[svgnames]{xcolor}

loads the package xcolor, which is more capable than the color package. The option svgnames allows to use many names such as Beige, Aqua, DarkViolet and a lot more.

Code: Select all

\newcommand*{\footnotemarkcolor}{red}

just defines a macro for the color, it's easier to change here than within another complex macro.

Code: Select all

\makeatletter
...
\makeatother

is necessary to use macros with an @ in the name, which usually mark internal macros.

Code: Select all

\renewcommand*{\@makefnmark}{\hbox{\@textsuperscript{%
  \color{\footnotemarkcolor}\normalfont\@thefnmark}}}

is a redefinition of the original LaTeX macro which prints out the footnote number. I just inserted the \color command.

Code: Select all

\usepackage{chngcntr}
\counterwithout{footnote}{chapter}

loads the chngcntr package, the second command removed the dependency of the footnote counter on the chapter counter.
