# How do I change the background color of a footer in beamer

I know just enough about beamer to be a danger to myself. I am trying to change the color of a footer in Boadilla and am struggling.

First, I have declared

\usecolortheme[named=black]{structure}


so that I get black text for frame titles. (Probably neither necessary nor terribly elegant.)

I would like the background of the footer to be a light blue with a yellow \hrule across the top. I am using the following code:

\makeatother
\setbeamertemplate{footline}
{
\leavevmode%
\hbox{%
\begin{beamercolorbox}[color=blue, wd=\paperwidth,ht=1in,dp=1ex,center]{title in head/foot}%
\end{beamercolorbox}}%
\vskip0pt%
}
\makeatletter


I can't seem to make the background color change. Any help available?

Welcome to TeX.sx! Please add a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}. –  Fran Feb 10 '13 at 3:10
The leads to the previous questions were very helpful. Here is the code that ended up working, in the hopes that it helps someone else further down the road: –  david robinson Feb 10 '13 at 13:56
