我实际上想重现以下维恩图：
为此，重要的是中央重叠区域为黄色；重现其他重叠颜色也很好......
这是我的尝试，绝对不行……
\documentclass[class=article,border=0pt]{standalone}
\usepackage{tikz}
\def\A{(0,0) circle (4cm)}
\def\B{(1,2) circle (4cm)}
\def\B{(2,0) circle (4cm)}
\begin{document}
\begin{tikzpicture}
\node[circle, fill=blue, opacity=.5, minimum size=4cm] (A) at (0,0) {};
\node[circle, fill=red, opacity=.5, minimum size=4cm] (B) at (1,2) {};
\node[circle, fill=green, opacity=.5, minimum size=4cm] (C) at (2,0) {};
\begin{scope}
\clip \A;
\fill[yellow] \B;
\end{scope}
\end{tikzpicture}
\end{document}
我想在使用 LuaLaTeX 编译的 Beamer 演示文稿中使用它

这是一个剪辑的解决方案在 tikz 中绘制具有不同颜色的椭圆作为它们的交点？
\documentclass[tikz,border=2mm]{standalone}
\usepackage{xcolor}
\begin{document}

\def\thirdcircle{(1.5,3) circle (3cm)}
\def\boundingbox{(-3,-3) rectangle (6,4.5)}

\end{scope}

\clip \thirdcircle;
\fill[batman] \boundingbox;

这是与 和 交点相关的解决方案pgfplots。可能有更简单的解决方案（例如使用裁剪），但这可能是一种替代方案。
