BLACK:
"Black color preferences point to black sex (not necessarily meaning black partners). These people are the misfits of the sex world and seek out each other in kinship. They tend to prefer perverted sex and are usually masochistic or sadistic in nature. They are moody people and often perform at their peak when under stress or during unhappy times. Police psychiatrists claim that sex offenders prefer the color black. And it is no coincidence that the uniform of mobsters and teenage gangs is black attire. "
Or they could just like listening to moody Brits sing sappy, depressing music. Jeez.
