Derive a class from CComboBox and override OnCtlColor. In OnCtlColor when the nCtlColor parameter is CTLCOLOR_LISTBOX, call the DC::SetBkColor method.

Maybe something like this:

HBRUSH CMyComboBox::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
    if (nCtlColor == CTLCOLOR_LISTBOX)
        pDC->SetBkColor(RGB(255, 0, 0));

    return CComboBox::OnCtlColor(pDC, pWnd, nCtlColor);
}

Inspiration taken from here and here.
