The Rock took on a bright spectrum of colors announcing Rainbow Week, a nine-day program put on by the Rainbow Alliance addressing LGBT issues. Members of the group painted the Rock at 10 p.m. Wednesday to make “an overt statement concerning the involvement of LGBT students at Northwestern,” said co-president Will Pearse. Rainbow Week continues Friday with “Games on the Lakefill” at 4 p.m. Rainbow Week ends Sunday.
