Brazilian Federation. The flag of the Federated States of Brazil is rectangular, with a green flag and a yellow diamond (cross) in the middle. The angles of the diamond are equidistant from the edge of the flag. The center of the diamond is a blue round ground, and the arched white belt divides the round ground into two parts. The leucorrhea is written in Portuguese green font: "Order and progress". From 1822, green and yellow are the colors of Brazil. Green symbolizes Brazil's vast jungle, and yellow symbolizes rich mineral deposits and resources. 1889 When Brazil established a federal republic, it cancelled the imperial national emblem on the original national flag and added a blue celestial sphere. The lower part of the celestial sphere symbolizes the southern hemisphere space, in which the Southern Cross is clearly visible.
