在mfc中创建自定义对话框

我需要在mfc中创建一个自定义对话框，该对话框的外观与通常的mfc对话框不同。例如，颜色应为蓝色，样式等。是否可能？我该怎么做

我用谷歌搜索了背景色：
看见

//CMyDlg.h
//Add a CBrush object

class CMyDlg : public CDialog
{
// Construction
    public:
    CTest2Dlg(CWnd* pParent = NULL);    // standard constructor
    CBrush  m_brush;
// Dialog Data


//initialize the brush with the desired color in the OnInitDialog() methodl  


BOOL CMyDlg::OnInitDialog()
{   
    m_brush.CreateSolidBrush(RGB(255,0,0));
    CDialog::OnInitDialog();

}

//Return the brush like this:

HBRUSH CMyDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor) 
{
//  HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

// TODO: Return a different brush if the default is not desired
    return m_brush;
}'
