A possible fix for this. It currently paints the background using clBackground, perhaps it should use something like clBtnFace? The constant clBackground =$80000001 which appears to be the DESKTOP background color (and not the application workspace background that was possibly originally implied).

{in themes.pas : TThemeServices.DrawElement}
        if Details.Part in [TABP_PANE, TABP_BODY] then
          FillWithColor(ARect, clBtnFace{clBackground}); //rr

You can use the panel and change color

Not that simple. The horizontal bevel just under the tabs still has wrong colour, and when the Panel is moved up to cover it, the bevel effect goes away.
