I am using a .cls template to generate a letterhead for my resume, by the following snippet:

\def\namefont{\huge\bf}
\def\@linename{\begingroup
\def\\{, }
{\namefont\@name}
\vskip 2pt
\fullline
\vskip 2pt
% where do you live?
% do nothing
}{%
\leavevmode\hbox to \textwidth
}%
}\par
}
\endgroup}


I need to recreate this for a different document, and I have done so like this:

\begin{flushleft}
\huge\bfseries Name
\setlength{\parindent}{0pt}
\end{flushleft}
\medskip\hrule height 0.5pt
\begin{flushright}
\end{flushright}


In the second version, there is a space between the huge name and the vertical line which I'd like to remove. Also the vertical line is black and not grey... How can I match the first version?

Note: This is only my second project in LaTeX.

Welcome to TeX.sx! Please add a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}. –  Kurt Dec 19 '12 at 15:41
Regarding the vertical space, you should remove \medskip. If that doesn't please you, add a negative space manually with \vskip-10pt, for example. –  Mafra Dec 19 '12 at 18:44

Simply remove the \medskip to get rid of the extra vertical space. For the color, use the package xcolor.

\documentclass{article}
\usepackage{xcolor}
\begin{document}

\begin{flushleft}
\huge\bfseries Name
\setlength{\parindent}{0pt}
\end{flushleft}
{\color{gray}\hrule height 0.5pt}
\begin{flushright}
