# Style of combs in pgfplots

I am using pgfplots to create comb figures such as the following.

\documentclass{article}
\usepackage{pgfplots}
\usepackage{xcolor}

\begin{document}

\begin{figure}
\centering
\begin{tikzpicture}
\begin{axis}
{(0,3) (1,2) (2,4) (3,1) (4,2)};
\end{axis}
\end{tikzpicture}
\end{figure}

\end{document}


I want to change the default color from blue to black. However, the above code only changes the outer boundary of the circles on the top of the combs, while the filled color is still blue. Is there anyone know how to change the inner color ?

The comb ends are markers that you can format via mark options

\documentclass{article}
\usepackage{pgfplots}

\begin{document}

\begin{figure}
\centering
\begin{tikzpicture}
\begin{axis}
