Description.

The reason the 32x32 icon is loaded is because constructor's call to
m_hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME);
only loads the 32x32 icon resource.

Solution.

To load the correct 16x16 resource LoadImage must be called as shown below.

/////////////////////////////////////////////////////////////////////////////
// CDlgSyntaxColourHtml message handlers
BOOL CDlgSyntaxColourHtml::OnInitDialog()
{
    TRACE( _T("CDlgSyntaxColourHtml::OnInitDialog()\n") );
    CDialog::OnInitDialog();

    // Set the icon for this dialog.  The framework does this automatically
    //  when the application's main window is not a dialog
    SetIcon(m_hIcon, TRUE);         // Set big icon
    HICON hIcon = (HICON)LoadImage(
                AfxGetInstanceHandle(),
                MAKEINTRESOURCE(IDR_MAINFRAME),
                IMAGE_ICON, 16, 16, LR_SHARED );
    ASSERT( hIcon );
    SetIcon( hIcon, FALSE );        // Set Small icon
