The flag of Brazil has a green field on which a large yellow rhombus is centred. A blue circle is placed within the rhombus, with white stars of five different sizes arranged in the shapes of various constellations of the Southern Hemisphere. A curved white band also runs through the blue circle, inscribed in green capital letters with the motto Ordem e Progresso ("Order and Progress").
This flag is sometimes called Auriverde which means "(of) gold and green". The next-to-last stanza of Castro Alves's Navio Negreiro, for example, uses that term.
The modern flag was officially adopted on November 19, 1889. The concept was the work of Raimundo Teixeira Mendes, with the collaboration of Miguel Lemos and Manuel Pereira Reis. The design was executed by Decio Vilares.
The current national flag and ensign maintains the same design with some minor changes. This 27-star version was adopted on May 12, 1992 (Law 8.421, May 11, 1992).
