In calling skin irony in indonesia. People will identify Papuans with blacks. People outside of Papua with whites. In fact, the black color is the basic color that is similar to the color of charcoal or show a color similar to charcoal. While the white warnah is like a basic color similar to the color of cotton. If referring to the average skin warnah of Indonesian (non-Papuan), then yellow (mongoloid), but in its use is identified with white.
In addition, the water is clear colored drink, many people call it with water. Though the white water that looks like milk or coconut milk. Such a thing has been widely accepted so we sometimes follow it. If it had been so fall in the language dikesalahan. In fact, if referring to KBBI understanding as described above.
Thus in terms of the use of Indonesian "Black Papuans" can be questioned. So far my assumption, the majority of Papuans are flattened-brown. Coeklat old or chocolate easy. Except for African-majority friends who are black races of negroid, as well as people in the Melanesian archipelago country such as Bougainville and solomon islands, although these two areas are not of the Negroid race but the majority of the people are black.
