Just some extra info :) Colour Several Lines It is correct that the above methods does not work for several lines, if you to be more than one line you can do: {\color{green} the text you want to write} This can however also be wrapped in a function so it is easier to use several places during edits, e.g., for colouring new text or whatever: \newcommand{\added}[1]{{\color{green}[added]:#1}} I prefer using tcolorbox thinking that in future you may want the background to be fashionable. I have given many options (which are not needed for this particular case) in the tcbset so that you can p...

To keep the effect of the color change local, you could use curly braces around the frame and that command, or \begingroup ... \endgroup . { \setbeamercolor{background canvas}{bg=violet} \begin{frame} % frame contents here \end{frame} } Put the \setbeamercolor command outside the frame. This will change the background colour for every subsequent frame. If you want to just change that slide, you can surround the frame and the command in {} Here's a complete example: \documentclass{beamer} \begin{document} \begin{frame}{A white frame} \end{frame} % Change all subsequent frames to violet \setbeamercolor{background canvas}{bg=violet!20} \begin{frame}{A violet frame} \end{frame} \begin{frame}{This frame is also violet} \end{frame} % But this frame only will be yellow: note { ... } around % the \setbeamercolor and the frame to limit the scope {\setbeamercolor{background canvas}{bg=ye...
