[Tex/LaTex] Changing background colour of poster

backgroundscolorposters

I want to change the background color of my poster but whatever command I try, nothing changes.

I am using this poster: http://www.latextemplates.com/template/baposter-landscape-poster.

This was included in the poster template:

\newcommand{\baposter@backgroundCmd}{\error{No background command defined. Use \background{...} to define background}}
\newcommand{\background}[1]{\renewcommand{\baposter@backgroundCmd}{#1}}

So I thought \background might work, it did not.

These are the relevant packages:

\documentclass[landscape,a0paper,fontscale=0.285]{baposter} % Adjust the font scale/size here

\usepackage{graphicx} % Required for including images
\graphicspath{{figures/}} % Directory in which figures are stored
\usepackage{xcolor}
\usepackage{colortbl}
\begin{document}

\begin{poster}

If anyone has any ideas that would be beyond ideal.

Best Answer

If you are happy with one-colour background it is quite simple:

\definecolor{BGcolour}{RGB}{40,40,40} % Define the colour named BGcolour
\begin{document}
\begin{poster}{
% other options
bgColorOne=BGcolour, % declare background colour
background=plain,    % set background to be plain colour
% other options}

% Poster code

\end{document}

Personal sidenotes:
Be carefull about transparency in your figures!
Be carefull about text and graphics colour match to the background!
I think that in most cases plain white (background=none) background and matte paper is the best option.
