Graphics, Figures & Tables ⇒ Option Clash for Package

[Curious George]

Trying to use the x11names option for xcolor in a beamer presentation, getting an "option clash" error. Example below. What is going on?

Danke/gracias/merci/thanks for your help.

This is the code.

Code: Select all

\documentclass{beamer}
\usepackage[x11names]{xcolor}
\begin{document}
begin{frame}
This is a test
\end{frame}
\end{document}

The following error occurs.

Code: Select all

Hi!

Because beamer loads xcolor, you have to use a trick to pass the option to the package.

Code: Select all

\PassOptionsToPackage{x11names}{xcolor}
\documentclass{beamer}
\begin{document}
\begin{frame}{Title}
  This is an x11 color: \fcolorbox{black}{SlateGray1}{test}.
\end{frame}
\end{document}

According to Section 2.6 of the beamer user guide Tom's approach can be simplified a bit.

Code: Select all

\documentclass[xcolor=x11names]{beamer}
\usepackage[T1]{fontenc}

\begin{document}

\begin{frame}{Title}
  This is an x11 color: \fcolorbox{black}{SlateGray1}{test}.
\end{frame}

\end{document}

More than one single option for xcolor would require additional braces for grouping.

Code: Select all

\documentclass[xcolor={dvipsnames,x11names}]{beamer}
