Question

我使用下列方法更改方程的颜色：

\documentclass{article} 
\usepackage{xcolor}

\everymath=\expandafter{\the\everymath\color{blue}} 
\AtBeginEnvironment{equation}{\color{blue}}
\AtBeginEnvironment{equation*}{\color{blue}}

\begin{document}
$inside\;math$
\begin{equation}
    inside\;math\;equation
\end{equation}

\begin{tabular}{c}
    inside tabular
\end{tabular}

\end{document} 

方程的颜色发生了变化，但 Tikz 图像中的表格和某些线条的颜色也发生了变化。我做错了什么？如何防止其他所有内容改变颜色？

根据@DavidCarlisle 的回答，这里有一个解决 $...$ 符号内部颜色变化问题的方法，即将它们重新定义为 \(...\)。欢迎改进和更正。

\documentclass{article} 
\usepackage{xcolor}

% change color inside equation environment
\AtBeginEnvironment{equation}{\color{blue}}
\AtBeginEnvironment{equation*}{\color{blue}}
% change color of math inside \(...\) and \[...\]
\AddToHook{cmd/(/after}{\color{blue}}
\AddToHook{cmd/[/after}{\color{blue}}

% redefine $...$ as \(...\)
\begingroup
\catcode`\$=\active
\protected\gdef$#1${\(#1\)}
\endgroup
\AtBeginDocument{\catcode`\$=\active}


\begin{document}

A possible trick is to change all $\$\;math\;\$$ to \(\setminus(math\setminus)\).
\begin{equation}
    inside\;math\;equation
\end{equation}

\begin{tabular}{c}
    inside tabular
\end{tabular}

\end{document} 

Answer 1

\everymath捕获所有内部数学模式，包括大多数垂直居中的构造，例如tabular，minipage。

\documentclass{article} 
\usepackage{xcolor}


\AtBeginEnvironment{equation}{\color{blue}}
\AtBeginEnvironment{equation*}{\color{blue}}
\AddToHook{cmd/(/after}{\color{blue}}

\begin{document}
\(inside\;math\)
\begin{equation}
    inside\;math\;equation
\end{equation}

\begin{tabular}{c}
    inside tabular
\end{tabular}

\end{document}
