I'm trying without success to use an enumeration with circled numbers but with different colors for each item: enter image description here

Could you help me please?

This is something that creates such colored lists. Ultimately you probably want to combine this with enumitem, but as you do not provide any code, here is a very basic version.

\documentclass{article}
\usepackage{circledsteps}
\usepackage{pgf}
\pgfkeys{/csteps/enumerate colors/.initial={"red","green!70!black","blue","orange","cyan",
    "magenta","teal","purple"}}
\renewcommand{\labelenumi}{%
\pgfmathtruncatemacro{\mydim}{dim({\pgfkeysvalueof{/csteps/enumerate colors}})}%
\ifnum\value{enumi}>\mydim
\textsf{\arabic{enumi}}%
\else
\pgfmathsetmacro{\mycolor}{{\pgfkeysvalueof{/csteps/enumerate colors}}[\value{enumi}-1]}%
\Circled[inner color=white,fill color=\mycolor,outer color=\mycolor]{\textsf{\arabic{enumi}}}%
\fi}
\begin{document}
\begin{enumerate}
 \item text
 \item text
 \item text
 \item text
\end{enumerate}
\end{document}

enter image description here

The colors are stored in the key /csteps/enumerate colors.

  • Thanks. Sorry, my document is a huge document so I did not put my code. I will try your solution, I have an error with other enumerate blocks now – Sébastien Mailfert Mar 31 '21 at 16:22
  • Your code works but (1) it changes all my other enumerate blocks and (2) there is a conflict with my style – Sébastien Mailfert Mar 31 '21 at 16:31

    @SébastienMailfert My crystal ball broke, so I didn't know what your code loads. As you say, my code works. If you want to have a more specific answer, you probably want to make your question more specific by adding a minimal example others can build on. –  Mar 31 '21 at 16:33

You have to define the colors, as shown in the MWE. If you exceed 9 enumeration items, you will exceed the circle (bullet) diameter.

\documentclass{article}
\usepackage{stackengine,xcolor,enumitem}
\newcommand\circnum[1]{\stackinset{c}{}{c}{.1ex}{\small\textcolor{white}{#1}}%
  {\abovebaseline[-.7ex]{\Huge\textcolor{\csname colenum#1\endcsname}{$\bullet$}}}}
\csdef{colenum1}{red}
\csdef{colenum2}{blue}
\csdef{colenum3}{cyan}
\csdef{colenum4}{orange}
\csdef{colenum5}{green!70!black}
\begin{document}

\begin{enumerate}[label=\protect\circnum{\theenumi}]
\item first
\item next
\item third
\item fourth
\item last
\end{enumerate}
\end{document}
