When transcluded content (for example, in the content boxes on Wikipedia portals) contains thumbnails, part of the region around the thumbnail takes on the default namespace background color, rather than the specified background color. See, for example: http://en.wikipedia.org/wiki/User:Ragesoss/template This occurs with Internet Explorer 6, Firefox 1.5, and Opera 8.51, at least. Filed by: http://en.wikipedia.org/wiki/User:Ragesoss
It actually has nothing to do with transcluded content. Rather, the box-header template used in most Wikipedia portals contains <div style="background: [some color];">. This specified color gets disrupted by using the "thumb" style with an image (i.e., [[image:imagefile.jpg|thumb|center|200px|here's the caption.]]).
