The ModelColumns:

  struct ModelColumns : public Gtk::TreeModelColumnRecord
  {
    ...
    Gtk::TreeModelColumn<Gdk::Color>    color_;
    ...
    
    ModelColumns() { ... add(color_); ...}
  };
  ModelColumns m_columns;

And where you create the cellrenderers:

  {
    Gtk::CellRendererText* pRenderer = Gtk::manage( new Gtk::CellRendererText() );

    int cols_count =m_TreeView.append_column(_("Color"), *pRenderer);
    Gtk::TreeViewColumn* pColumn =m_TreeView.get_column(cols_count-1);

    pColumn->add_attribute(pRenderer->property_text(), m_columns.color);
    
    pColumn->add_attribute(pRenderer->property_foreground_gdk(), m_columns.color_);
    pColumn->add_attribute(pRenderer->property_weight(), m_columns.weight_);
  }
