According to Edward Telles, three different systems related to "racial classification" along the White-Black continuum are used in Brazil. The first is the Census System, which distinguishes three categories: "branco" (White), "pardo", and "preto". The second is the popular social system that uses many different categories, including the ambiguous term "moreno" (literally meaning "tanned", "brunette", or "with an olive complexion"). The third is the Black movement, which distinguishes only two categories, summing up "pardos" and "pretos" ("blacks", lowercase) as "negros" ("Blacks", with capital initial), and putting all others as "whites". More recently, the term "afrodescendente" has been adopted for use, but it is restricted to very formal discourse, such as governmental or academic discussions, being viewed by some as a cultural imposition from the "politically correct speech" common in the United States.
