# Setting background colour for part of a page

I am designing a business card using the memoir class and hints given here and am trying out various background effects. Specifically, I would like to change the background for the last third of the card to another colour. Because the colour needs to bleed to the edge, an option involving tables is not suitable. Short of inserting an image and overwriting it, is there a more elegant way to achieve this?

When I understood your requirements correctly you need anyway a 90mm x 52mm PDF as a result. Therefore I would recommend to you to "draw" the card using TikZ. There you can set the background colors as filled rectangles. Use the preview package to minimize the resulting PDF page. The code below uses standalone to do this automatically.

TikZ supports a lot of graphical features like shadings etc., so you shouldn't run into any limitations. See this question if you want to draw on the background of a normal page instead.

\documentclass[border=0mm]{standalone}
\usepackage{tikz}
\begin{document}
\sffamily
\begin{tikzpicture}
% Define size and default background color of card:
\useasboundingbox [fill=blue!10] (0,0) rectangle (90mm,52mm);
% Background of last third
\fill [red] (60mm,0mm) rectangle (90mm,52mm);
% Place the text freely. You can also place tabulars or \parboxes
\node [right] at (10mm,30mm) {John Doe};
\node [right] at (10mm,25mm) {Example Cooperation};
\node [right] at (10mm,20mm) {John.Doe@example.com};
\end{tikzpicture}
\end{document}

Thank you very much for your solution and also for introducing me to the standalone documentclass. It will be very helpful for a graphic rich manuscript I am working on. Perhaps you should popularize the standalone documentclass and package via a TUGBoat article if you have not already done so. –  chandra Mar 1 '11 at 16:11
@chandra: Thanks you. It's a nice idea to write a TUGBoat article. However ATM I very busy writing my PhD thesis. Note that I published a new version of standalone yesterday which allows the preview border to be set using and class option, e.g. border=0mm. –  Martin Scharrer Mar 1 '11 at 16:30

you can use simple colorboxes

\documentclass{article}
\usepackage{xcolor,lipsum}
\begin{document}

\lipsum[1]

\noindent\fboxsep=0pt%
\colorbox{blue!10}{\parbox[c][0.5\textwidth][c]{0.7\textwidth}{%
\centering\large\tabular{l}
John Doe\\Example Cooperation\\John.Doe@example.com
\endtabular}}%
\colorbox{red}{\parbox[c][0.5\textwidth][c]{0.3\textwidth}{\rule{\linewidth}{0pt}}}

\end{document}

You could use eso-pic, atbegshi, everyshi (older) or textpos (easy to use) for placing a color filled rectangle into the background.

Alternatively, you could use TikZ and the current page node. Here's an example where I used this method for headings and page headers: Fancy chapter headings with TikZ. See Comment #20 for an example with colored headers. It could be modified like desired.
