Every single American having heard "black" would never think of an actual color but rather of a person of color. The same happens with "white". As if tho it would be too lame to call people just people. We always have to add some strange tags thinking that they would describe somebody better.
Look at this white chick, the other day I heard some black men talking. At the same time I heard the white saying "black dude" many times, but none of them was dressed in black or white.
Nonetheless, the idea of calling people colors sounds misleading because actual color of skin is not even close to white, black or yellow. It is not just incorrect to call a person like that but impolite too.
Does the color terminology really necessary these days? John Black, Rita White, Xuyan Yellow... Why people are named as colors?
Color terminology was used to label races and origin. It has spread extremelly among American society between the 18th and 20th centuries when people from different countries were trying to find their luck in the USA. Soon it became to difficult and unnecessary to try identifying every single origin so not to bother themselves too much, people started calling one another by the color of skin each had which at that time was usually just Blak or White. This phenomenon is closely connected to the black men slavery when the white were considered to be the chosen ones. Saying what color are you was considered to be a good way to distinguish between races and, at the same time, to emphasize your social status.
However, in the 21st century referring to a person as a part of a particular race is still very popular. It is sad that humans did not go too far from those time when you needed to tell the color of your skin to be identified as part of one or another social class. It is true that the only way to tell who you really are is adding the color of your skin near yourname, otherwise, how people would know if you really a human being, uhm?
