鉴于此 MWE
\documentclass[11pt]{book}
\usepackage{xcolor}
\usepackage{pifont} %http : // ctan.org/pkg/pifont
\newcommand{\cmark}{\textcolor{green!80!black}{\ding{51}}}
\newcommand{\xmark}{\textcolor{red}{\ding{55}}}
\begin{document}
\cmark \underline{A}
\cmark \underline{B}
\end{document}
使用 lualatex 进行编译可获得预期的输出
但make4ht -ulm default -a debug report.tex "mathjax,htm"使用
它确实给出了这个警告
l.10 --- TeX4ht warning --- missing \Configure{HColor}{green!80!black}{...} (in
LaTeX: \\color@green!80!black ) ---
Unsupported font pzdr
但总是第一次输入会失败，但是\cmark之后每次使用都可以正常进行。
以下是原始 HTML
<!DOCTYPE html>

这已在 Brave 浏览器和 Firefox 上进行了检查。
为什么这种情况只发生在第一个，如何纠正？如何\Configure{HColor}修复这个问题？
更新
\newcommand{\cmark}{\textcolor{green!80!black}{\ding{51}}}我注意到当更改为时它工作正常\newcommand{\cmark}{\textcolor{green}{\ding{51}}}
因此，tex4ht 似乎对颜色混合的支持不够好。没什么大不了的。我现在只会\textcolor{green}在 tex4ht 中使用，并在 PDF 中使用。\textcolor{green!80!black}

答案1
这似乎是 TeX4ht 中对颜色规范的支持存在错误green!80!black。我找到了文档中颜色规范的位置并进行了修复。尝试以下版本xcolor.4ht：

宏中需要进行修复\get!HColor，它调用包含颜色名称的控制序列，但未检查该名称是否存在。由于这种类型的规范不存在该名称，因此该控制序列的参数最终会进入文档，而不是被吃掉。
结果如下：
