\hl 带有自定义颜色、换行符和数学

Question

我想将包含数学符号的文本高度设为灰色，并允许换行。基于这很好的帖子，我试过：

\documentclass{article}
\usepackage{xcolor}
\usepackage{soul}
\newcommand{\mathcolorbox}[2]{\colorbox{#1}{$\displaystyle #2$}}
\newcommand{\hlfancy}[2]{\sethlcolor{#1}\hl{#2}}

\begin{document}
This works: \hlfancy{gray}{colored $a=b$ math}.  
This does not:  \hlfancy{gray!60}{colored $a=b$ math}.  
\end{document}

Answer 1

这是一个解决方案：

\documentclass{article}
\usepackage[svgnames]{xcolor}
\usepackage{soul}

\newcommand{\mathcolorbox}[2]{\colorbox{#1}{$\displaystyle #2$}}
\newcommand{\hlfancy}[2]{\colorlet{hlcolor}{#1}\sethlcolor{hlcolor}\hl{#2}}

\begin{document}

This works: \hlfancy{gray}{colored $a=b$ math}.
This also works: \hlfancy{gray!30!Lavender}{colored $a=b$ math}.

\end{document}
