# How to change seagull color theme alert text to non-bold

Some beamer color themes (as seagull) define alert text as bold font.

However, sold font alerts are annoying when one uses overlay (eg: \onslide+<2->), because bold text takes more space than normal text, which breaks the illusion of an animation.

To change alert from normal to bold, we can use the command

\setbeamerfont{alerted text}{series=\bfseries}


(see here). Unfortunately, I was unable to revert this by using something like

\setbeamerfont{alerted text}{series=\normaltext}


I don't know if this is because this command is wrong or if it is because it can't override seagull's settings.

Does someone know a trick to set non-bold text with the \alert command while using seagull color theme?

• you need \setbeamerfont{alerted text}{series=\mdseries} or \setbeamerfont{alerted text}{series=\normalfont} – Old Nick Nov 22 '13 at 10:29
• Thanks @dcmst! Actually the trick was to use a separate line to set series= and fg=. – glaugier Nov 22 '13 at 10:34

There is no \normaltext command, it is possible to change the series of the font with the \mdseries command, which sets it to medium, or with the \normalfont command, which sets the font series, shape and familiy to the default value.

So what you need is something like:

\documentclass{beamer}
\usecolortheme{seagull}

There is also a \textnormal{} macro, which is the bracketed version of \normalfont (as \textmd{} is the bracketed version of mdseries).
