希望你一切顺利。我想设置 Beamer（citep 和 citet）中 cite 命令的颜色属性（例如蓝色），但我不知道该怎么做。我该怎么做？这是我的代码。

您几乎在代码注释中找到答案，请尝试进行以下微小修改：
\let\oldcitet=\citet
\let\oldcitep=\citep
\renewcommand{\citet}[1]{\textcolor[rgb]{0,0,1}{\oldcitet{#1}}}
\renewcommand{\citep}[1]{\textcolor[rgb]{0,0,1}{\oldcitep{#1}}}

无关：
你不需要
\usepackage{xcolor}
\usepackage{hyperref}
\usepackage{color}
因为 beamer 已经提供了这些功能。
