Located in tropical Brazil, it is mainly white. What is the reason?

The reason why this area is dominated by whites is that it became a Portuguese colony because of the great maritime discoveries of14th century and15th century.

In the era of great navigation, Spain and Portugal, which had the first-Mover advantage, occupied a large number of colonies in the world. At that time, Portugal occupied the whole of Brazil, while Spain annexed the whole of South America except Brazil.
