Beamer - define highlight color

Question

I am using Beamer for the first time. I use setbeamercolor to change most of the colors of the miniframes and so on. But how to I change the color of the highlighted text in the headline and table of content. Right now it is bright green.

\documentclass[xcolor=dvipsnames,compress,12pt]{beamer}%
\mode<presentation>

%% General document %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\usepackage{beamerthemeshadow}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

%% Beamer Layout %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\useoutertheme[subsection=false,shadow]{miniframes}
\usecolortheme{seahorse}
\usecolortheme{rose}
\usefonttheme{serif}

Answer 1

To change theme-specific highlighting colours then, in addition to the settings applied by \usecolortheme, you can use specific \setbeamercolor commands such as:

\setbeamercolor{section in toc shaded}{fg=red}
\setbeamercolor{section in toc}{fg=blue}

to change the colour of text in the table of contents (assuming by 'highlighted' you mean 'not shaded'?) and

\setbeamercolor{section in head/foot}{fg=red}

to change the colour of section text in the headline.

See section 17 of the beamer user guide and beamercolorthemedefault.sty for more details on colours and the names of areas/characters that can be specified. The latter also indicates the parent/child relationships.
