Dado este 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}
Compilar com lualatex fornece o resultado esperado
Mas usar make4ht -ulm default -a debug report.tex "mathjax,htm"dá
Ele dá esse aviso
l.10 --- TeX4ht warning --- missing \Configure{HColor}{green!80!black}{...} (in
LaTeX: \\color@green!80!black ) ---
Unsupported font pzdr
Mas é sempre a primeira entrada que falha, mas todos os usos \cmarkposteriores funcionam bem.
Aqui está o HTML bruto

Isso foi verificado no navegador Brave e no Firefox.
Por que isso acontece apenas no primeiro e como corrigir? Como usar \Configure{HColor}para consertar isso?
Atualizar
Percebi que funcionou bem ao mudar \newcommand{\cmark}{\textcolor{green!80!black}{\ding{51}}}para\newcommand{\cmark}{\textcolor{green}{\ding{51}}}
Portanto, parece que a mistura de cores não é bem suportada no tex4ht. Não é grande coisa. Vou usar apenas \textcolor{green}em tex4ht e \textcolor{green!80!black}em PDF por enquanto.

Isto parece ser um erro no suporte para especificações de cores na forma do green!80!blackTeX4ht. Descobri onde a especificação de cores entra no documento e corrigi-a. Experimente esta versão de xcolor.4ht:

A correção foi necessária na \get!HColormacro, ela chamava uma sequência de controle que continha o nome da cor sem verificar se ela existe. Como não existe para este tipo de especificação, o parâmetro daquela sequência de controle vai parar no documento, ao invés de ser consumido.
Este é o resultado:
