To colour things at run-time, based on data in your model, use 
gtk_tree_view_column_set_cell_data_func() on each column you want to
colour:
http://developer.gnome.org/doc/API/2.0/gtk/GtkTreeViewColumn.html#gtk-tree-view-column-set-cell-data-func

This will get called for every cell, each time it's rendered, and it's
in here that you set the renderer's background to your desired colour.
