Taste the Rainbow
In the Cosmic Era changing the color of a person's skin is remarkably easy: a brief biogenetic mod, and a mineral supplment. This can be a minor cosmetic change, such as adding a permanent tan or quite dramatic, such as becoming an opaque albino (ghost white complexion without the issues associated with albinism) or any other solid, often vibrant color.
Kuros - black skinned, not African, but black. Popular in the underground community, especially death revelers, and those of a more negative aspect.
Shiros - opaque white, as in printer paper white. Shiros is very popular among fashion models.
Akas - Red, in varying shades. A favorite among strippers and sex workers (conceals rashes and sores well) but it most well known for the Sausage Cart Man.
Kies - Yellow, fairly uncommon, usually only seen when a performance group is doing rainbow work. Sometimes seen as a sign of political militant apathy.
Aos - Blue, a perennial favorite of artists, painters, performers, and musicians. Origin of the term 'smurfs' and 'blue movies' as one of the first real applications of holovid tech involved aos sex play. Their skin color allowed the pornographic display to jump obscenity and porn/sexuality limited laws in place at the time.
Midoris - Green, another popular color, especially among urban primitives, neo-hippies, ecological activists and seacology dwellers.
Momoiros - Pink, Hello Kitty candy pink, popular among groups like Ko Girls and other predominantly female groups that strongly associate themselves with perceived youth, innocence and anime style seduction.
