Barrio, Purok or Barangay means Village. When we refer to the minorities we used cultural minorities if we try to be politically correct but usually we refer to them depending where they come from. Usually we say Igorots for people from the Mt Province but politely we say from the Highlands. But words like that, Mangyans and other minority tribes does not offend as they are Tribal names. Others are now offended and ashamed to be called as such, but like you say coloured people to dark ones afraid to offend or be branded racist.
