您可以使用以下方式更改脚注的颜色
\setbeamercolor{author in head/foot}{bg=black}
\setbeamercolor{title in head/foot}{bg=blue}
其他一些评论：
如果你的评论中有换行符必须在每行前面加一个 %。有些换行符会导致编译错误，有些换行符会导致幻灯片输出不正确
\thispagestyle{empty}不是很具有光束效果，我会改用plain框架选项。同理
\addtocounter{framenumber}{-1}，也可以用noframenumbering。最好先使用
\title和，然后您将获得合理的 pdf 元信息。\author\begin{document}
