Change the colour......

[stevesh]

You can find this in your stylesheet, and separate the .center column out and add background-color:#XXXXXX;


.centerColumn, #bannerOne, #bannerTwo, #bannerThree, #bannerFour, #bannerFive, #bannerSix {
padding: 0.8em;
}

so:

.centerColumn {
padding: 0.8em;
background-color:#XXXXXX;
}
