Beamer how to change color of infolines and frame title

Question

How could I change the color of color of infolines and frame title in beamer. I am using this now

\documentclass[xcolor=dvipsnames]{beamer}
\usetheme{CambridgeUS}
\useinnertheme{rectangles}
\useoutertheme{infolines}
\usecolortheme[named=Brown]{structure} 

I need to change the color from red to brown. [named=Brown] doesn't work for \useoutertheme{infolines}. This is my current output. I also need to change the background of frame title (mouse pointer)

Answer 1

Redefine the frametitle, section in head/foot, author in head/foot colors, and date in head/foot colors:

\documentclass[xcolor=dvipsnames]{beamer}
\usetheme{CambridgeUS}
\useinnertheme{rectangles}
\useoutertheme{infolines}

\setbeamercolor{frametitle}{fg=Brown,bg=Brown!20}
\setbeamercolor{section in head/foot}{bg=Brown}
\setbeamercolor{author in head/foot}{bg=Brown}
\setbeamercolor{date in head/foot}{fg=Brown}

\begin{document}

\begin{frame}
\frametitle{A test frame}
\end{frame}

\end{document}

The same could have been achieved with:

\setbeamercolor*{palette tertiary}{bg=Brown}
\setbeamercolor{frametitle}{fg=Brown,bg=Brown!20}
