i have a question: why we don't call asian yellow?
@topic it is wrong when referring to African(people with a culture and ethnicity) African never used the color classification.
when referring to people with no culture and ethnic group it is not wrong.
ps: we don't have tribal marks and i know plenty others Ethnicity which don't have tribal marks. js saying
to conclude you can every aliens(non-Africans) can be classified or called/referred by the color of his skin they even enjoy that.
my 2cents.

Please note below:

Previous studies of genetic and craniometric traits have found higher levels of within-population diversity in sub-Saharan Africa compared to other geographic regions. This study examines regional differences in within-population diversity of human skin color. Published data on skin reflectance were collected for 98 male samples from eight geographic regions: sub-Saharan Africa, North Africa, Europe, West Asia, Southwest Asia, South Asia, Australasia, and the New World. Regional differences in local within-population diversity were examined using two measures of variability: the sample variance and the sample coefficient of variation. For both measures, the average level of within-population diversity is higher in sub-Saharan Africa than in other geographic regions. This difference persists even after adjusting for a correlation between within-population diversity and distance from the equator. Though affected by natural selection, skin color variation shows the same pattern of higher African diversity as found with other traits.

Skin color variation is highest amongst "SUB SAHARAN" populations compared to non African natives. Maybe because humans have been involving in Africa for the last 200,000 years before a small groupz ventured out to populate the rest of the world suggesting that this would be the natural selecting ground for diversity in skin color.

Attempts have been made to break the so called peoples of sub saharan Africa into races of their own based on skin color using nonsensical terms such as "negroid" "congoid", "capoid", "Aethipoid" and the rest to denote certain groups of sub saharan Africans into distinct races. However this continues to prove problematic because there is no specific scientific/verifiable point in which characteristics of one race of humans stops and the other begins....(excluding admixture models)

Thanx for you information morpheus.

God has grouped us that way. He divided Israel into tribal territories and forbade them from mingling with outsiders. Nothing wrong with colours.
