[pstricks] arrows no longer colored in \code blocks

[Hensh, Richard]

Dear Herbert,

Many years ago, I generated custom vector fields using the \code command in PSTricks. You can see various examples here:

  https://users.math.msu.edu/users/hensh/courses/234/fall2022/lectures/exam2/16.1.pdf

Unfortunately, when I try to generate new vector fields, the arrows are no longer affected by my color selections. The MWE below is part of a \multido loop, and I need to set the arrow color to match the line color on-the-fly.

\documentclass{standalone}
\usepackage{pstricks-add}
\begin{document}
\psset{unit=30mm}
\begin{pspicture}(-2,-2)(2,2)
  \pscustom[linewidth=2pt,arrowscale=1.5]{%
  \arrows{->}
  \code{%
  0 0 5 5 ArrowA %
  30 30 110 75 ArrowB %
  1 0 0 setrgbcolor % Only sets the line color to red.
  lineto %
  stroke %
  }
  }
\end{pspicture}
\end{document}

The above code generates a red line with a black arrow. I must be able to do this within the \code block. Can you help?

thanks
rick
