Peace,
The term "Black & Brown" comes from one of the many hip hop groups under the Sun Tzu Cadre record label that is controlled by the Gods in D-Mecca.
The Nation of Gods and Earths see the original family composed of Black, Brown and Yellow people. This means everyone who is non-white is actually a "shade" of black. So for those with understanding, the black man is "original", the brown man is "original" and the yellow man is "original." So at the end of the day we view the world as having two types of people which are "original" i.e. black, brown and yellow and also "colored" i.e. white people. There are people of all the various "shades" of black in the Nation of Gods and Earths. It's actually quite amusing to see a Chinese, Polynesian or Latino brotha refer to himself as God because it's something you don't see very often. They are all right and exact to see it that way though.
Peace
Precise Infinite Peace Allah
