Page Layout ⇒ beamer | Background Colors in Boxes

[soTo]

Hi everyone,

I am trying to change the background color of my beamer boxes, but it always remains white.

Here is example:

Code: Select all

\documentclass{beamer}

\usepackage{color}

\usepackage[english]{babel}
\usepackage[applemac]{inputenc}
\usepackage[T1]{fontenc}

\usepackage{graphicx}
\usepackage{multirow}

\usetheme{classic} 
\usefonttheme{serif}

\setbeamertemplate{navigation symbols}{} % no navigation symbols
\setbeamertemplate{itemize item}[ball]
\setbeamertemplate{itemize subitem}[triangle]
\setbeamertemplate{blocks}[rounded][shadow=true]

\begin{document}

\begin{alertblock}{Test}
  Test
\end{alertblock}
	
\begin{beamerboxesrounded}[upper=yellow,lower=blue,shadow=true]{Test}
  Test
\end{beamerboxesrounded}

\begin{block}{Bloc arrondi et ombré}
  Un bloc avec option rounded et shadow
\end{block}

\end{document}

The background colors of the different boxes are always white, whatever I do.

Some help would be appreciated !

Cheers

I have finally found the answer.

I have defined in the preamble:

Code: Select all

\setbeamercolor{upcol}{fg=black,bg=yellow}
\setbeamercolor{lowcol}{fg=black,bg=yellow!40}

Then, with the call

Code: Select all

\begin{beamerboxesrounded}[upper=upcol,lower=lowcol,shadow=true]
test
\end{beamerboxesrounded}

it worked perfectly.

Cheers
