The national flag of Brazil (Portuguese: Bandeira do Brasil), often colloquially called the Auriverde (The Gold and Green),[1] is a blue disc depicting a starry sky spanned by a curved band inscribed with the national motto, within a gold rhombus, on a green field. Brazil officially adopted this design for its national flag on November 19, 1889, replacing the flag of the Empire of Brazil. The concept was the work of Raimundo Teixeira Mendes, with the collaboration of Miguel Lemos, Manuel Pereira Reis and Décio Villares
