RGB 到 CMYK 等效颜色

Question

TeXnicians，如何将 RGB 颜色值转换为等效的 CMYK 颜色值？请参阅以下 MWE 文件：

\documentclass[draft]{book}
\usepackage{color,}

\definecolor{rgbcolor}{rgb}{0.686,0.059,0.569}
%\definecolor{cmykcolor}{cmyk}{0, 0, 0, 0}


\begin{document}
\textcolor{rgbcolor}{This is RGB color}

%\textcolor{cmykcolor}{This is Equivalent for converted RGB to CMYK color}

\end{document}

Answer 1

您可以使用xcolor包

\documentclass[draft]{book}
\usepackage{xcolor}

\definecolor{rgbcolor}{rgb}{0.686,0.059,0.569} %\definecolor{cmykcolor}{cmyk}{0, 0, 0, 0}
\convertcolorspec{named}{rgbcolor}{cmyk}\tmp
\definecolor{cmykcolor}{cmyk}{\tmp}
\begin{document}
    \textcolor{rgbcolor}{This is RGB color}

    \textcolor{cmykcolor}{This is Equivalent for converted RGB to CMYK color}.
    The computed values are: \tmp.
\end{document}
