如何实现这个目标？

Answer 1

如果您不想使用颜色package并且想要启动自动着色，那么您可以使用pdfcsplainOPmac 而不是 LaTeX 的格式：

\input opmac \localcolor

\def\registerword#1{\sdef{w:#1}{{\Red#1}}%
   \expandafter\mubyte\csname w:#1\endcsname \space#1\endmubyte}

\mubytein=0
\registerword { is }
\registerword {paragraph}
\registerword {text}
\mubytein=1

This is the sample paragraph text here. 
Other text is tested. How are you?

Answer 2

当我想让部分文本显示为红色时，我通常会在序言中放入这个宏：

 \newcommand{\red}[1]{\textcolor{red}{#1}}

在文中我使用：

Some normal (black) text \red{the part of the text that I want to be red} some other text.

Answer 3

\documentclass{article}
\usepackage{color}
\begin{document}

    This is the sample \verb!!\textcolor{red}{paragraph}\verb!! text here.

\end{document}
