Can I change the color of NoteBook, and Tabs ?

Hi !

This is the code:

        clr=self.toppanel.GetBackgroundColour()
        self.datanotebook = wxNotebook(self, -1, style=0)
        self.datanotebook.SetBackgroundColour(clr) # I'll try to set
        for i in range(len(self.NBNames)):
            nb=wxPanel(self.datanotebook, -1)
            nb.SetBackgroundColour(clr)
            self.datanotebook.AddPage(nb,self.NBNames[i])
            self.NBObjs.append(nb)
            sizer=wxBoxSizer(wxHORIZONTAL)
            self.NBSizers.append(sizer)
            nb.SetAutoLayout(1)
            nb.SetSizer(sizer)

The toppanel's color is the Windows ButtonFace Color (silver).
But the NB and it's items are get White Color.

Why ? How I can set the color ?

Thanx:
