I want to put a grid in the background of every page (for use in classroom). I found the package pagegrid. I can change the color of the red/blue grid, looks beautiful, but I need to change the color of the help lines to light-gray, otherwise it's too dark to use for my students.
Another possibility would be to get rid of the helplines alltogether, but this didn't work either.
MWE:
\documentclass[a4paper,11pt]{article}
\usepackage[step=5mm,firstcolor=gray,arrows=false]{pagegrid}
\pagegridsetup{top-left}
\begin{document}
Test
\end{document}
\documentclass{...}and ending with\end{document}. – Philipp Imhof Mar 04 '20 at 12:58
