Problem: The concept of race in Brazil is complex. A Brazilian child was never automatically identified with the racial type of one or both of his or her parents, nor were there only two categories to choose from. Between an individual of unmixed West African descent and a very light mulatto individual, more than a dozen racial categories were acknowledged, based on various combinations of hair color, hair texture, eye color, and skin color. These types grade into each other like the colors of the spectrum, and no one category stands significantly isolated from the rest. In Brazil, people are classified by appearance, not heredity.
How are people in Brazil classified?
The answer is the following: by appearance
