\documentclass{article}
\usepackage{pstricks-add}%
\pagestyle{empty}
\defineTColor[hatchsep=0.004\linewidth,fillstyle=crosshatch]{TBlue}{blue}

\begin{document}

\begin{pspicture}(5,5)
\psframe*[linecolor=magenta](4,4)
\pscircle[linestyle=none,style=TBlue](2,2){2}
\pscircle[linestyle=none,fillcolor=magenta,fillstyle=solid](2,2){1.75}
\end{pspicture}

\end{document}
