Sorry i have no knowledge about how to use themes at all. All i remember is that i did consider the css enginge broken when i looked into it years ago as it did not consider subclasses to match super classes and would suggest to fix that before working with it. Also i would expect that the Layout Spy (shift-ctrl-alt-f9) shows which css classes an element does adhere to. But i can't see helpful information there. Maybe improve that tool first?

i.e. this CSS entry did the coloring:

CTabFolder Canvas {
	background-color: #F8F8F8;
}

eclipse.platform.ui/bundles/org.eclipse.ui.themes/css/e4_default_win.css

Line 74 in b06fb47

CTabFolder Canvas {

Adding that to e4_preview_win.css solves this problem - but i don't know what else it will color too.
