Banner of Portuguese language

This flag of Portuguese language is not good, because it is bound to two countries and its middle is overwhelmed contrary to edges. This flag is better, but it still contains Portuguese green-red bicolour and thus is unacceptable in kingdom of Iberia. This is simple image, but it is more banner of arms than flag. So I made another symbol of Portuguese language. Inspired by this flag of Portugal I changed a half of it to Brazilian colors. The blue is neither Portuguese nor Brazilian, but from flag of CPLP. Brazil is left because of alphabetical order and because Brazil is west from Portugal.
