Beamer loads xcolor internally, so you need to pass xcolor options to beamer:
\documentclass[hyperref={pdfpagelabels=false},dvipsnames]{beamer}
\usecolortheme{whale}
\usecolortheme[named=BrickRed]{structure}
\usepackage{lmodern}
\begin{document}
\begin{frame}{title}
normal
\alert{alerted}
\end{frame}
\end{document}
