Depending on your definition of “Colonized or Controlled”, the Ottomans never completely conquered what is today Saudi Arabia - they conquered Hejaz and parts of the Gulf province but never (as far as I am aware) Najd and other parts of the center and south.
Turkey is considered part of Europe here so shouldnt Saudi Arabia be darker shade of blue because of the Ottomans?
