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. Oct 24, 2018 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! Oct 24, 2018 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. Oct 24, 2018 at 21:36

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}

enter image description here

  • 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? Oct 24, 2018 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? Oct 24, 2018 at 21:34
  • @luciadefinetti Please see my edited answer. I guessed a few more elements which might be between the lines. Oct 24, 2018 at 21:44

    @marmot :) Crystal ball factory: \documentclass{standalone} \usepackage{tikzlings} \begin{document} \foreach \x in {1,...,100}{\tikz{\tikzling[crystalball];}} \end{document} Oct 24, 2018 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 Oct 24, 2018 at 22:25
