获取 tikzpictures 的 beamer 调色板

Question

我无法使这里提出的解决方案发挥作用：访问由 Beamer 颜色主题定义的独立 tikzpicture 的颜色

\documentclass[hyperref={pdfpagelabels=false},xcolor=x11names,compress]{beamer}
\usetheme{Boadilla}
\usepackage{tikz}%Mind map
\usetikzlibrary{mindmap,trees} %Mind map
\usepackage{media9,multimedia,comment,booktabs,datetime}

\begin{document}
\begin{frame}
\frametitle{Literature Review}
%\tikzset{every node/.append style={scale=2}}
\resizebox{0.9\textwidth}{!}{
\hspace{50pt}\begin{tikzpicture}
 %\tikzstyle{every node}=[font=\Large,level distance=8cm]
    \path[mindmap,concept color=DeepSkyBlue4,text=white,font=\sf\bf,text width=5cm,
        level 1/.append style={level distance=6cm,sibling angle=60},
        level 2/.append style={level distance=4cm},]

        node[concept] {Learning}[clockwise from=0]
        child[concept color=DeepSkyBlue4] {
            node[concept] {practical}[clockwise from=90]
            child { node[concept] {algorithms} [clockwise from=40]
            child { node[concept] {databases} }
            child { node[concept] {WWW} }}
            child { node[concept] {data structures} }
        }  
        child[concept color=red,text=black] {
            node[concept] {applied}[clockwise from=360]
            child { node[concept,level distance=16cm,sibling angle=60] {databases} }
        }
        child[concept color=red,text=black] { 
            node[concept] {technical} 
        }
        child[concept color=red,text=black] { 
            node[concept,text width=2cm] {theoretical} 
        };
\end{tikzpicture}}
\end{frame}

\end{document}

我怎样才能red用所选主题设置的内容（或自定义的内容）替换上面的内容\setbeamercolor*{palette tertiary}{fg=black,bg=black!10}？我想对各种 tikzpicture、pgfplots 等执行此操作。

Answer 1

我不知道为什么有些beamer颜色可用（例如structure.fg），而有些则不可用。但你总是可以定义基于 beamer 主题的颜色。这样，当您更改 beamer 主题时，所有颜色都会改变。

后

\usebeamercolor{block title alerted}
\colorlet{color1}{bg}

color1将等于block title alerted.bg颜色。您可以重复此行以定义更多颜色。下面的代码显示了使用此解决方案的示例。

Claudio Fiandrino 在如何获取投影仪中颜色主题颜色的实际值？其中\ccft使用新命令（从模板创建颜色）来定义普通的颜色基于投影机那些。

\documentclass[hyperref={pdfpagelabels=false},xcolor=x11names,compress]{beamer}
\usetheme{Boadilla}
\usepackage{tikz}%Mind map
\usetikzlibrary{mindmap,trees} %Mind map
\usepackage{media9,multimedia,comment,booktabs,datetime}

\usebeamercolor{block title alerted}
\colorlet{color1}{bg}
\usebeamercolor{block body}
\colorlet{color2}{bg}
\colorlet{color3}{bg!30!color1}

\setbeamercolor*{palette tertiary}{fg=red,bg=black!10}
\usebeamercolor{palette tertiary}
\colorlet{color4}{bg}

       level 2/.append style={level distance=4cm},]
