The way I did it in my program was via a gtk_cell)renderer_text
property..
http://developer.gnome.org/doc/API/2.0/gtk/GtkCellRendererText.html
if you look at the property's there you see you can set "foreground-gdk"

code:
renderer =  gtk_cell_renderer_text_new();
column = gtk_tree_view_column_new_with_attributes("Priority", renderer,
"text" , PRIOSTR,"strikethrough", DONE,"foreground-gdk", COLOR, NULL);

(COLOR is an enum for the row with the color setting)
 

so I've added an GdkColor row to my gtk_(tree/list)_store.
and now I can set the color off every row in the list.

I don't get this to work either..  (by letting youre callback function
return with FALSE you don't stop the signal). but the selection would
then take place AFTER whatever you did. and that isn't great either.
so can't help you here
