How to use \usepackage{pst-barcode}

You can pass the options for xcolor via pstricks:

\documentclass{article}
\usepackage[dvipsnames,x11names]{pstricks}% Options for xcolor
\usepackage{pst-barcode}
\begin{document}
\begin{pspicture}(3.5,1.2in)
\psbarcode[linecolor=red]{1234567}{includetext inkspread=0.5}{ean8}
\end{pspicture}
\end{document}

xcolor itself loads by default color

And with

\psbarcode[linecolor=red]{1613198400317}{includetext inkspread=0.5}{ean13}
