Or, alternatively (retaining xcolor's features):

\documentclass{article}

\usepackage[dvipsnames]{pstricks}

\begin{document}

\psline[linecolor=JungleGreen,linewidth=2pt](3,0)

\end{document}


Another solution is to add the line
\ExecuteOptions{dvipsnames}
in the color.cfg file.
In this case, the second line may be changed into
\usepackage{pstricks}
Thus, individual TeX input files don't have to be touched.

The "usenames" option is sometimes misunderstood;
it doesn't load any color names in color.sty, but it makes
color names that are defined by \DefineNamedColor available
to the "normal" syntax.
It is obsolete in xcolor.sty.
