Are Creole people dark skin?

The Creoles of color are a historic ethnic group of Creole people that developed in the former ... show that the term Créole was used variously at different times to refer to white people, mixed-race people, and black people, including slaves.

I am from New Orleans, so Creole is light skin, almost white, practically . But a lot of dark people like to call themselves creole.... 

If they are. 

Like American or Australian or Zimbabwean people.
