Comment 33 for bug 899878

Jakey_TheSnake: "but the front page still looks terrible thanks to the hardcoded background: http://i.imgur.com/Z1J9K42.png"

So anyone fluent with Gimp could fix that part, even if you aren't a coder: edit or redraw <http://bazaar.launchpad.net/~ubuntuone-control-tower/software-center/trunk/view/head:/data/ui/gtk3/art/stipple.png> ("download file") so that it is stipple on a transparent background, rather than stipple on a hard-coded grey background.

Once we've done that, the colors won't need to be hard-coded for the sake of the stipple background, so maybe removing those CSS rules is enough to fix the bug.
