Where did you get the numbers for France? I though that it not possible to do any ethnic census there?
Perhaps it could have been done by asking for countries of birth for the parents/grandparents.
Also when you are saying colonies, is it the former colonies (North Africa, Sub-Saharan Africa, Ex-Indochina) or the current overseas departments (in the Carribean, Guiana in South America and in the Indian Ocean)?
