我怎样才能使箭头变为红色并且线条保持为蓝色？

Question

我试图画一条中间有红色箭头的蓝线，但一切都只显示为蓝色。以下是我的代码，我不知道如何修复它。请帮助我。谢谢！

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{arrows}
\usepackage{tkz-euclide}
\usetikzlibrary{decorations.markings}

\begin{document}
\begin{tikzpicture}
    \tkzDefPoint(-3,0){A}
    \tkzDefPoint(-2,2){B}
    \draw[Blue, thick, postaction={decorate, red, decoration={
    markings,
    mark=at position 0.5 with {\arrow{stealth}}}}] (A)--(B);
\end{tikzpicture}
\end{document}
