The way in which the default system works for prefixes and user banners is either they use the default color palette or the colors are hard coded leaving only one option which is to overwrite them using EXTRA.css.
The next update for [XB] we will be implementing a easier way to style prefixes and user banners as it seems like it is a troublesome area when doing a custom skin.
We would like any input you may have if any.
