# Changing color of a beamer presentation (Szeged-dove)

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!

• Can you maybe ask a separate question about your font problem and include a minimal working example (MWE) of what does not work? It is very hard to diagnose why a code is not working when we don't see the code. – user36296 Oct 24 '18 at 21:24
• I'll try and edit this one to make it clearer but if I don't succed I'll surely write a new one! – lucia de finetti Oct 24 '18 at 21:33
• Please ask for the font problem in a separate question. It is better for the site if a question does not mix different problems. Imagine if some future user also wants to change the colour. Then we can direct him to this question. But if your question contains a mixture if things, it will be more difficult for future users to find a solution. – user36296 Oct 24 '18 at 21:36
• I see, I'll do it now! – lucia de finetti Oct 24 '18 at 21:39

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}

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

\begin{document}

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

\end{document}


• Thanks very much! Is there a way so that the text that appears between separation lines (chapter names and dots on the header; title of the presentation and author name on the footer) is of the same color "mycolor" instead of black? – lucia de finetti Oct 24 '18 at 21:32
• @luciadefinetti Sure, you can do things like \setbeamercolor{title in head/foot}{fg=mycolor}. Can you make a minimal working example (MWE) that contains all elements for which you want to change the colour? – user36296 Oct 24 '18 at 21:34
• @luciadefinetti Please see my edited answer. I guessed a few more elements which might be between the lines. – user36296 Oct 24 '18 at 21:44
• @marmot :) Crystal ball factory: \documentclass{standalone} \usepackage{tikzlings} \begin{document} \foreach \x in {1,...,100}{\tikz{\tikzling[crystalball];}} \end{document} – user36296 Oct 24 '18 at 22:22
• @marmot it is not yet on ctan, but I will submit it soon. At the moment it is only available from github.com/samcarter/tikzlings – user36296 Oct 24 '18 at 22:25
