在此 MWE 中
\documentclass{article}
\usepackage{xcolor}
\usepackage{pifont}% http://ctan.org/pkg/pifont
\newcommand{\cmark}{\ding{51}}
\newcommand{\xmark}{\ding{55}}
\begin{document}
Why this is red \textcolor{red}{\cmark}
But not this one? {\color{red}\cmark}
\end{document}
在使用编译时，PDF 中两者都\cmark显示为红色，lualatex但在 HTML 中，只有第一个显示为红色，第二个仍为默认的黑色文本。使用编译为 HTML make4ht foo.tex
在 Linux 上使用 TL 2018
答案1
编辑：我已将color选项添加到 TeX4ht 源。TeX Live 更新后，应该可以使用以下方法获取颜色：
$ make4ht filename.tex "color"
原始答案中包含的警告仍然相关 - 这可能会导致一些问题，因此仅在必要时使用它。
原始答案：
您可以尝试以下版本color.4ht：

我添加了以下声明：
\pend:defI\@declaredcolor{\ifdefined\end:def:color\end:def:color\else\aftergroup\b:textcolor\fi\a:textcolor\def\end:def:color{\b:textcolor}}
它会在命令前添加一个代码\@declaredcolor，供 内部使用\color。我认为它的功能有点脆弱，这就是为什么默认情况下不使用它的原因。\end:def:color如果在一个 TeX 组中使用了多个命令，则会执行该命令。它会为前一个命令\color插入结束标记。会插入开始标记并将当前颜色保存到 CSS 文件中。最后一个命令必须在组关闭后使用 命令完成。\color\:textcolor\a:textcolor\color\aftergroup
请看示例：
Why this is red \textcolor{red}{\cmark}
But not this one? {\color{red}\cmark\color{green}\xmark}
生成的 HTML：
<!--l. 10--><p class="noindent" >Why this is red <span id="textcolor1"><span
class="pzdr-">✓</span></span>
</p><!--l. 12--><p class="indent" > But not this one? <span id="textcolor2"><span
class="pzdr-">✓</span></span><span id="textcolor3"><span
class="pzdr-">✗</span></span>
</p>
和 CSS：
span#textcolor1{color:#FF0000}
span#textcolor2{color:#FF0000}
span#textcolor3{color:#00FF00}
还有一张图片：
此解决方案有一个大问题，这也是为什么它不是默认使用的。以下消息来自tex4ht讨论此事的消息来源：
The \Verb!\color{red}! instruction might be problematic since it does not on its own determine the extent of the text to be colored. As因此，其效果可以跨越逻辑界限。这违背了标记语言的哲学，尤其是 XML 的哲学。
It is possible to implement the \Verb!\color{...}! feature but I'm not sure it is desirable to do so. I think it is preferable to expect用户使用 \Verb!\textcolor{red}{...}! 形式的命令来获取代码片段。
看看这个例子：
\color{brown} Fist paragraph.
Second paragraph.
您可能希望两个段落都是棕色的，但只有第一个段落可以正常工作。问题是颜色更改标签将插入第一个段落内，但它将在段落末尾隐式关闭。结束标签根本不会插入，因为没有要关闭的组。
