When I compile this document using pdflatex
, my chapter's (and sections and subsections, too) titles are, respectively, blue (here defined as 'azzurro') and gold.
I would like that all titles and subtitles be black.
This is the document:
\documentclass[envcountsame,envcountchap]{svmono}
%\usepackage[latin1]{inputenc}
\usepackage[utf8]{inputenc}
\usepackage{eurosym}
\usepackage{makeidx} % allows index generation
\usepackage{graphicx} % standard LaTeX graphics tool
\usepackage{xtab} % when including figure files
\usepackage{multicol}
\usepackage{qtree}
\usepackage{booktabs}
\usepackage{latexsym}
\usepackage{psfig} % used for the two-column index
\usepackage[bottom]{footmisc} % places footnotes at page bottom
\usepackage[italian]{babel}
\usepackage{my_listings}
\usepackage[hyphens]{url}
\usepackage{algorithm}
\usepackage{algorithmic}
\usepackage{multirow}

In this way the file is compiled like the attached image.
When I replace the colors with 'black' as
\definecolor{black}{rgb}{0,0,0}
it give me these errors:
Package xcolor Error: Undefined color gold
Package xcolor Error: Undefined color azzurro
What I can do?
