How to set custom background for linum mode?

I'm trying to get the same left margin as textmate mac-classic theme, i've setup my custom face for fringe, but got some problems with left margin in linum-mode. If i try M-x customize-face linum background it sets my color only for linum-numbers, but not the whole left margin(the whole margin still have the color of the default background). How to set it right?
