Glossary link's color

Question

How can I change the color of glossary links when using glossaries along with hyperref? I just want to change glossary link colors not all links.

Answer 1

Normally the link color is set via the option linkcolor of the package hyperref. To influence only the link color of glossaries you must redefine the command \glstextformat. In the documentation you can find:

The way the link text is displayed depends on

\glstextformat{⟨text⟩}

For example, to make all link text appear in a sans-serif font, do:

\renewcommand*{\glstextformat}[1]{\textsf{#1}}

In relation to this comment here an example:

\documentclass[10pt,a4paper]{report}
\usepackage{xcolor}
\usepackage[colorlinks=true]{hyperref}
\usepackage[xindy]{glossaries}
\renewcommand*{\glstextformat}[1]{\textcolor{green}{#1}}

\makeglossaries
\newglossaryentry{A}{name={A}, description={A is A}}
\newglossaryentry{AA}{name={AA}, description={AA is AA}}
\newglossaryentry{B}{name={B}, description={B is B}}
\newglossaryentry{C}{name={C}, description={C is C}}
\newglossaryentry{CC}{name={CC}, description={CC is CC}}

\begin{document}
Here I cite either \gls{A}, \gls{AA}, \gls{B}, \gls{C} or \gls{CC}.
I want three groups in the glossary output, indicated by \textbf{A},
\textbf{B} and \textbf{C} with entries in them according to their initial letter.

\printglossary[style=indexgroup]
\end{document}
