[Tex/LaTex] LaTeX beamer beaver color theme not working

beamer

When I put \usecolortheme{beaver} in the preamble I get grey slides as opposed to the expected beaver color theme. If I use any other color theme, they work fine. The beamercolorthemebeaver.sty file is properly installed. Why is this happening? Why do all color themes work, except this one?

Could it be a color issue more than a theme color issue?

Sorry, adding sample code below.

\documentclass{beamer}
\usetheme{Montpellier}
\usecolortheme{beaver}

\begin{document}

  \begin{frame}
  \frametitle{This is a slide example}
  \end{frame}

\end{document}

The result is that instead of having the corresponding color theme, it comes out on a scale of grays. Issue happens only with beaver color theme.

the example slide

Best Answer

Your example results to a coloured frame as the picture below shows.

However your output is the result after a usage of the option gray of the package (x)color. So I guess you are using somewhere in your preamble something like this

\usepackage[gray]{xcolor}

or

\PassOptionsToPackage{gray}{xcolor}
