分项文本不符合 tcbset 颜色

Question

这是我的mwe投影机。如您所见，在hlcard环境中，普通文本会改变其颜色，但不会itemized environment。

    \newtcolorbox{hlcard}[1][]{%

        #1

\begin{document}
\begin{frame}{}
    \begin{hlcard}[]
        Hello from normal text
        \begin{itemize}
            \item Hello from itemized text
        \end{itemize}
    \end{hlcard}
\end{frame}

\end{document}

我在这里做错了什么？

作为 Werners 回答的后续此主题，我建议您在颜色框开始时将颜色更改为自定义颜色（MWE 中的白色），并normal color在结束时改回。
