You can change the font size using the \fontsize command; using \textcolor you can change the text color. An example (run it with XeLaTeX):
\documentclass[12pt]{article}
\usepackage{fontspec}
\usepackage{xcolor}
\usepackage{varwidth}
\newenvironment{Verse}
{\center\varwidth{\linewidth}\fontsize{18}{21.6}\selectfont}
{\endvarwidth\endcenter}
\usepackage{lipsum}
\begin{document}
\lipsum[1]
\begin{Verse}
\textcolor{red}{\fontsize{8}{9.6}\selectfont\bfseries A line in bold red color}\\
foo bar\\
baz
\end{Verse}
\end{document}
In the preamble of your document, you could define a command to change the font size, color and series for the line of text:
\newcommand\RedLine[1]{%
\textcolor{red}{\fontsize{8}{9.6}\selectfont\bfseries#1}
}
and then use it in the body of your document like
\RedLine{text with different font attributes}

Not really an answer to your question. But there are special classes for presentations (which is what you want to do) that change fonts etc.
The most famous is probably
beamerbut there are also some specifically for transparencies if you want that. Have a look at the catalogue.
