更改块中枚举项的颜色

Question

基本上，我正在尝试改变 beamer 中块环境中枚举项、子项和子子项的前景色。

在以下文件中，该行

\AtBeginEnvironment{block}{\setbeamercolor{enumerate item}{fg=esi-green}}

和他们的朋友们* 应该 *让它工作。除了，他们不...请注意，影响块内项目内项目前景的线条工作正常。老实说，我没主意了。问题很可能出在“颜色主题”代码示例中，但我不知道它到底在哪里，也不知道我做错了什么。

颜色主题

谢谢您的回答。

说实话，我不明白其中的逻辑，但方形枚举模板使用了颜色item projected。如果您将其添加到颜色主题中，则可以更改枚举项。

\documentclass{beamer}

\mode<presentation>
\setbeamertemplate{footline}[frame number]
\setbeamercovered{transparent}
\usetheme{ESI}
\setbeamertemplate{frametitlecontinuation} {\insertcontinuationcount}



\AtBeginEnvironment{block}{%
    \setbeamercolor{itemize item}{fg=esi-green}
    \setbeamercolor{itemize subitem}{fg=esi-green}
    \setbeamercolor{itemize subsubitem}{fg=esi-green}
    \setbeamercolor{enumerate item}{fg=esi-green, bg=red}
    \setbeamercolor{enumerate subitem}{fg=esi-green}
    \setbeamercolor{enumerate subsubitem}{fg=esi-green}
    \setbeamercolor{item projected}{fg=white, bg=esi-green}
}

\begin{document}
\begin{frame}
\begin{block}{titel}
\begin{enumerate}
\item Level 1
    \begin{enumerate}
    \item Level 2
        \begin{enumerate}
        \item Level 3
        \end{enumerate}
    \end{enumerate}
\end{enumerate}
