How do i change the format of the black dots in the itemize environment using enumitem?

Question

I´m new to the "enumitem" package and would like to make an itemize with blue triangles, instead of the regular black dots. How do i do this? either as a global setting in my preamble or as a local setting for each itemize environment.

I want it to be like the picture, but just in a blue color.

Answer 1

You can use code like this:

\documentclass[12pt,twoside,portrait,a4paper]{article}    
\usepackage{tikz}
\usepackage{enumerate}    
\usepackage[utf8]{vietnam}    
\newcommand{\myarrow}{    
\begin{tikzpicture}    
\fill[green](90:.1)--(0:.2)--(270:.1)--cycle;    
\end{tikzpicture}    
}
\begin{document}    
\begin{enumerate}[\myarrow]    
\item This firts    
\item This second    
\end{enumerate}    
\end{document}

Answer 2

A version without TikZ, but with enumitem, amssymb and xcolor:

\documentclass[]{article}

\usepackage{enumitem}
\usepackage{amssymb}
\usepackage{xcolor}

\newcommand*\myarrow
  {%
    \leavevmode
    \rlap{\kern.1em\textcolor{gray}{$\blacktriangleright$}}%
    \raise.1em\hbox{\textcolor{orange}{$\blacktriangleright$}}%
    \kern.1em
  }

\begin{document}
\begin{itemize}[label=\myarrow]
  \item Foo
  \item Bar
  \item Baz
\end{itemize}
\end{document}

A tikz picture can be set as label for enumerate

 \setlist[enumerate]{label=\protect\tikz{\fill[gray] (0,-0.05)--+(-0.1,-0.1)--+(-0.1,0.1)--cycle;\fill[orange] (0,0)--(-0.1,-0.1)--(-0.1,0.1)--cycle;}}

\documentclass{article}
\usepackage{enumitem}
\usepackage{tikz}
\setlist[enumerate]{label=\protect\tikz{\fill[gray] (0,-0.05)--+(-0.1,-0.1)--+(-0.1,0.1)--cycle;\fill[orange] (0,0)--(-0.1,-0.1)--(-0.1,0.1)--cycle;}}

\begin{document}
\begin{enumerate}
\item first
\item second
\item third
\end{enumerate}
\end{document}
