Complete Style

Hello! I'm trying to make a layout for a network-type journal that uses the custom friend color option heavily. I've narrowed down the css coding down to the .inner-entry-userpic where I can manipulate the icon on the friend's page, but even if I use 'background: transparent !important;', I can't seem to see my custom friend colors.

Is the custom colors option not compatible with Complete Style? If it is, am I using the wrong code bit to manipulate the transparency?

Thank you!
