Document Classes ⇒ [beamer] How to change the color and style of the toc?

[topfklao]

Hi!

I want to change the "sqaures" of the table of contents, which is embeeded with the following command (\tableofcontents). By default the color of the squares is blue. But I want another color!

So far I'm:

\setbeamertemplate{sections/subsections in toc}[square] # set the squares
\setbeamercolor{section in toc square}{bg=white,fg=black} # set the color? This is not working


Thanks for every answer!
