I would like to put a red circle before the beginning of a paragraph.

This code does that effect but there are a lot of errors:

\paragraph{{\tikz{\draw[red,fill=red] (0,0) circle (.5ex);}} PARAGRAPH}

What I have to do in order to avoid errors?

Just like marmots, sometimes TikZ needs a bit of protection. ;-)

\documentclass{article}
\usepackage{tikz}
\begin{document}
\paragraph{\protect\tikz{\fill[red] (0,0) circle (.5ex);} PARAGRAPH}
\end{document}

enter image description here

Of course, for red bullets you do not need TikZ, you could just load xcolor and do \paragraph{\textcolor{red}{\textbullet} PARAGRAPH} to achieve virtually the same. I am assuming that you want to do more fancy things.

  • +1 for the last paragraph, assuming that here "fancy" mean really "needlessly convoluted" :) – Fran Nov 6 '18 at 21:52
  • @Fran I was more thinking about marmots, bears and penguins, and koalas. All of them need a bit protection...;-) – marmot Nov 6 '18 at 22:33
  • I sympathize with that. Also the snorers readers are endangered because of lack of space in our natural hábitats. – Fran Nov 6 '18 at 22:53
  • @Fran That's what I thought (given that you produced such a nice certificate for marmot students ;-) – marmot Nov 6 '18 at 22:58
