如何让标签颜色从环境中更改为边框颜色？在此示例中，如何将标签颜色更改为绿色（如定义环境）？

Answer 1

下列的这个答案，下面基于 MWE 提出了一种可能的解决方案标题：

\documentclass{article}
\usepackage{caption}
\usepackage{xcolor}

\captionsetup[table]{labelfont={color=green!50!black},font={color=green}}
\captionsetup[figure]{labelfont={color=red},font={color=red!50}}

\begin{document}

\begin{table}[htp]
  \caption{A table}
\end{table}

\begin{figure}[htp]
  \caption{A figure}
\end{figure}

\end{document}

个人想法：我总是觉得green它太亮了，通常很难看，我更喜欢 green!50!black。

编辑-改进的答案

让我们引用标题的手册第 4 页。

\captionsetup 只对当前环境有影响，这一点很重要。因此，如果您只想更改当前图形或表格的设置，只需将 \captionsetup 命令放在图形或表格内 \caption 命令之前即可。

\captionsetup因此，我们的想法是，在每个里面定义一个特定的\newenvironment。在 MWE 中，这些\newenvironment是mySpecialEnvironment。

我也用过这个答案让所有标题保持在同一页面上。

\documentclass{article}
\usepackage{xcolor}
\usepackage{caption}
\captionsetup[table]{labelfont={color=green!50!black},font={color=green}}
\captionsetup[figure]{labelfont={color=red},font={color=red!50}}

\newenvironment{mySpecialEnvironment}
  {\captionsetup[table]{labelfont={color=purple!75!black},font={color=purple}}
  \captionsetup[figure]{labelfont={color=orange!75!black},font={color=orange}}
  }
  {}

\setcounter{topnumber}{8}
\setcounter{bottomnumber}{8}
\setcounter{totalnumber}{8}
\begin{document}
\begin{table}[!ht]
  \caption{A table}
\end{table}
\begin{figure}[!ht]
  \caption{A figure}
\end{figure}
\begin{mySpecialEnvironment}
  \begin{table}[!ht]
    \caption{A table}
  \end{table}
  \begin{figure}[!ht]
    \caption{A figure}
  \end{figure}
\end{mySpecialEnvironment}
\begin{figure}[!ht]
\caption{A figure}
\end{figure}
\begin{table}[!ht]
\caption{A table}
\end{table}
\begin{figure}[!ht]
  \caption{A figure}
\end{figure}
\begin{mySpecialEnvironment}
  \begin{table}[!ht]
    \caption{A table}
  \end{table}
  \begin{figure}[!ht]
    \caption{A figure}
  \end{figure}
\end{mySpecialEnvironment}
\begin{figure}[!ht]
\caption{A figure}
\end{figure}
\end{document}

笔记：请注意，可能还有其他答案使用\makeatletter和\makeatother类似于您的\declaretheorem，但在这里我没有寻找这些选项。

Answer 2

这是我的最终答案。非常感谢@FHZ

这个答案使用

\AtBeginEnvironment{<envname>}{
  \captionsetup{...}
}

定义每个环境中所有字幕的呈现方式。
