I'm trying to obtain that the blocks on one half of the poster have, say, red background, and in the other half have, say, green background.

Is that possible?


  • Please help us help you and add a minimal working example (MWE) that illustrates your problem. Reproducing the problem and finding out what the issue is will be much easier when we see compilable code, starting with \documentclass{...} and ending with \end{document}.

  • Look up block styles on page 13 of the manual. Dec 9, 2016 at 4:31

The background color of the blocks is blockbodybgcolor, so you can simply redefine that colour as you see fit in your document, using \colorlet{blockbodybgcolor}{<colorname>}. Similarly, the background color of the block title is blocktitlebgcolor, so you can change that as well, if you wish.

enter image description here

\author{D. Ude}
\block{A}{This has the default colour}

\block{B}{This is green}
{ % start a group to keep the change of title background color local
\block{C}{As is this, but the title has red background}
} % end that group

\block{D}{This is cyan}
