You code is working perfectly fine for me

I did this

Defined a public Brush

CBrush *brush;

in

CTestDlg

which is my Dialog Class

Then Initialized this in constructor

brush = new CBrush(RGB(49,49,49));

And then this goes into

HBRUSH CTestDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
	if(pWnd->GetDlgCtrlID()==IDC_CHECK1)
	{

		pDC->SetTextColor(RGB(0, 255, 0));
 		pDC->SetBkColor(RGB(0, 0, 0));
 		return (HBRUSH)(brush->GetSafeHandle());
	}
	HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

	return hbr;
}
