TabControl's background color

Hi,

I'm fighting with it for a while... How can I change this control's background color (and only background color)? It should be easy and straightforward but I guess it is not...

To be precised, I don't want to change TabPage's background :-/ What I mean is the background before any TabPage is added.

Sorry for stupid explanation but I run out of ideas and want to avoid creating colored panel on top of it until first tab is added.

Hope you have some ideas.
