Changing color of a beamer presentation (Szeged-dove)

Question

I am working on beamer presentation, Szeged theme and dove colortheme. Basically, I'd like to change the color of all the dove-colored lines and the text that's between them to a RGB value set with \definecolor without changing anything else.

Thanks very much in advance for any help!

Answer 1

The colour of the lines is controlled by separation line colour. You can change this colour to whatever colour you have defined:

\documentclass{beamer}

\definecolor{mycolor}{RGB}{255,0,0}

\usetheme{Szeged}
\usecolortheme{dove}

\setbeamercolor{separation line}{bg=mycolor}

\setbeamercolor{title in head/foot}{fg=mycolor}
\setbeamercolor{institute in head/foot}{fg=mycolor}
\setbeamercolor{section in head/foot}{fg=mycolor}

\title{text}
\author{names}
\institute{institute}

\begin{document}

\section{title}
\begin{frame}
    \frametitle{title}
    abc
\end{frame} 

\end{document}
