我在用
\usetheme{Boadilla}
\usecolortheme{orchid}
\setbeamercolor{itemize item}{fg=white!80!black}
\setbeamercolor{itemize subitem}{fg=white!80!black}
将列表项的项目符号颜色更改为灰色。
然而,这会导致环境中的子弹block
难以看清(灰绿色背景上的灰色子弹)。
有没有办法让 LaTeX 在块环境之外绘制灰色项目符号,并structure
为块内的每个列表绘制彩色项目符号?

是的,您可以使用etoolbox
包并\AtBeginEnvironment
根据需要在块内设置颜色;一个小例子,改变和的block
颜色exampleblock
:
\documentclass{beamer}
\usecolortheme{orchid}
\usepackage{etoolbox}
\AtBeginEnvironment{block}{
\setbeamercolor{itemize item}{fg=orange!70!black}
\setbeamercolor{itemize subitem}{fg=orange!70!black}
}
\AtBeginEnvironment{exampleblock}{
\setbeamercolor{itemize item}{fg=cyan}
\setbeamercolor{itemize subitem}{fg=cyan}
}
\setbeamercolor{itemize item}{fg=white!80!black}
\setbeamercolor{itemize subitem}{fg=white!80!black}
