I have been writing a document and I decided to use the fancyheader... Then after I recompile the file (view dvi) i got 48 errors and they were: undefined color 'BLACK' Any idea? I wonder if the error is because of my preamble.. I have the following in the preamble: \usepackage{sectsty} \chapterfont{\mdseries\centering} \sectionfont{\mdseries\centering} \subsectionfont{\mdseries\textit} \subsubsectionfont{\mdseries\textit} \paragraphfont{\mdseries\textit} \renewcommand{\theequation}{\thesection.\arabic{equation}} \renewcommand{\@seccntformat}[1]{} Any idea?
