您可以在文件中beamercolorthemedefault.sty
找到颜色定义:
\definecolor{beamer@blendedblue}{rgb}{0.2,0.2,0.7}
\setbeamercolor{structure}{fg=beamer@blendedblue}
structure
例如,颜色的使用
\setbeamercolor{palette primary}{use=structure,fg=structure.fg}
\setbeamercolor{titlelike}{parent=structure}
\setbeamercolor{title}{parent=titlelike}
\documentclass{beamer}
\definecolor{foo}{rgb}{0.2,0.2,0.7}
\begin{document}
\begin{frame}{Color here}\large
\color{foo}Color here defined by hand
\end{frame}
\end{document}
