I really don't know why my index is red. I don't use color in any part of the code. Someone can help me?I have to finish it by tomorrow!!Thank you very much

The code is:

\documentclass[12pt,a4paper,oneside,openright]{book}

\usepackage{packages} % inserisce tutti le macro necessarie per il
% funzionamento

\usepackage{algorithm}
\usepackage{algpseudocode}
\usepackage{graphicx}
\usepackage{array}
\usepackage{amssymb}
\usepackage{booktabs}
\usepackage{subfloat}
\usepackage{subfig}
\usepackage{rotating}
\usepackage{amsthm}
\usepackage{caption}

\theoremstyle{plain}

\setstretch{1.3}  %interlinea, mettere 1 per singola da usarsi per le bozze!!!

• Please make your code compilable (if possible), or at least complete it with \documentclass{...}, the required \usepackage's, \begin{document}, and \end{document}. That may seem tedious to you, but think of the extra work it represents for TeX.SX users willing to give you a hand. Help them help you: remove that one hurdle between you and a solution to your problem. – user31729 Mar 25 '14 at 5:49
• my code compiling in that way.. I just have other files like capthers or introductions in different files..the code I wrote is from the beginning to the end of my file and it works like that – user1938352 Mar 25 '14 at 5:52
• \usepackage{packages} can not work on somebody else's machine, as well as frontesp, a package I do not know. Did you mean frontespizio? As well, nobody except of you can \input{introd} etc. It is very tedious to comment that lines or to create dummy files for those people which want to help you. – user31729 Mar 25 '14 at 5:54
• in each "introd" or "chapter" I just write the thesis (no package or other things). To compile is enough to create these files, even if they are empty.I removed the frontespizio part, but the index is still red! – user1938352 Mar 25 '14 at 6:01
• @user1938352: have a look if somewhere in these unknown (for us) files there is something like \usepackage[colorlinks,linkcolor=red]{hyperref}. With the snippet provided, there are no definitions that makes your table of contents (I suppose you're referring to the table of contents and not index, though in italian they are "indice") red. Likely, you will find this definition in the file packages.sty that I'm not aware of. – Claudio Fiandrino Mar 25 '14 at 6:11
