Create new CWnd base class  CBackGround

handle WM_ERASEBKGND as below in your new class.

BOOL CBackGround::OnEraseBkgnd(CDC* pDC)
{
      BOOL result;
      result = CWnd::OnEraseBkgnd(pDC);
      RECT inside;
      GetClientRect(&inside);
      pDC->FillSolidRect(&inside, 0x000000FF); // red background
      return result;
}

in your mainframe.h file include the header for the new class
and create a protected member

say

      CBackGround m_background;

and
Subclass this client window in your mainframe's OnCreate function as

m_background.SubclassWindow(m_hWndMDIClient);

now you have a red background.
