使用宏改变列表中字符串分隔符的颜色

Question

更新2（解决方案）：

感谢令人惊叹的 Sašo (https://tex.stackexchange.com/users/16819/sašo-Živanović)，现在有一个针对此问题的有效解决方案。此代码允许将 HTML 和 CSS 标记为内联和代码块。请参阅下面的最小工作示例。

Sašo 的解决方案是添加以下内容来识别:。

\makeatletter
\def\colorcolonother#1#2{%
  \expandafter\ifx\the\lst@token:%
    \color{#1}%
  \else
    \color{#2}%
  \fi
}
\makeatother

然后在CSS的定义样式中添加：

\lstdefinestyle{css}
{
  stringstyle=\colorcolonother{editorBlue}{editorPurple},

最小工作示例（MWE）：

\documentclass{scrreprt}
\usepackage[dvipsnames,cmyk]{xcolor}
\usepackage{listings}
% --------------------------------------------------------------
% Color definitions
% --------------------------------------------------------------
\definecolor{editorGray}{cmyk}{0, 0, 0, 0.2}
\definecolor{editorBlue}{cmyk}{1, 0.35, 0, 0}
\definecolor{editorPink}{cmyk}{0, 1, 0, 0}
\definecolor{editorDarkOrange}{cmyk}{0, 0.8, 0.9, 0}
\definecolor{editorPurple}{cmyk}{0.75, 1, 0, 0}

\makeatletter
\def\colorcolonother#1#2{%
  \expandafter\ifx\the\lst@token:%
    \color{#1}%
  \else
    \color{#2}%
  \fi
}
\makeatother
