子图：标题中的数字和换行符的颜色（投影仪）

在我的子图标题之前，Latex 自动将 (a) (b) 放在前面，颜色为蓝色。 有没有办法将 (a) 和 (b) 的颜色改为黑色？

另外，有没有办法在副标题中输入换行符？以下是我使用的标题：

\documentclass[xcolor={dvipsnames}]{beamer}

对于您使用的软件包的一些评论：

  • \usepackage{amsmath}如果您使用过，则不需要\usepackage{mathtools}。
  • dsfont和都bbm提供“黑板”字体。我不会混合这两种字体，因为它们非常相似，所以请只选择一种。
  • 你不需要\usepackage{color}，因为beamer已经使用了xcolor。

解决方案如下：您需要的是\setbeamercolor{caption name}{fg=black}。

  \setbeamertemplate{caption}[numbered]
  \setbeamertemplate{itemize items}[ball]
  \setbeamertemplate{itemize subitem}[triangle]

}

\usepackage[english]{babel}

\definecolor{darkblue}{rgb}{0.0,0.0,0.66}
\usepackage{subfig}

\setbeamercolor{caption name}{fg=black}

\begin{document}

\section{Sample}
\begin{frame}{Sample}
\begin{figure}
  \centering
  \subfloat[This is figure a with a very very very very very long caption]{\includegraphics[width=0.49\textwidth]{example-image}}%
  \subfloat[This is figure b]{\includegraphics[width=0.49\textwidth]{example-image}}
