Colored text

Commands that control foreground and background colors need

   \usepackage[dvips]{color}

after the \documentclass line but before \begin{document}.

• \textcolor{colorname}{text} writes text in a color which can be specified by name (black, white, red, green, blue or a color name you've defined), RGB components, or grayscale.
• \colorbox{colorname}{text} writes text in a box with a colored background.
• \fcolorbox{framecolor}{boxcolor}{text} writes text in a colored frame.
• \pagecolor{colorname} sets the color of the page's background.
• \definecolor{colorname}{color specification} lets you define new color names.

\definecolor{gold}{rgb}{0.85,.66,0}
This is in \textcolor{red}{red} and this box is \colorbox{gold}{gold}.
Text color can be set using RGB values 
(\textcolor[rgb]{0,1,0}{like so}), or \textcolor[gray]{0.2}{shades} 
\textcolor[gray]{0.5}{of} \textcolor[gray]{0.8}{grey}.
