The same color?

Though I'm not a fan, I was always under the impression that the hip hop duo Salt-n-Pepa was comprised of an African American and a Caucasian, hence the name.

It recently has come to my attention that this is not the case. Cheryl James(now known as Cheryl Wray) and Sandra Denton are both black.

I don't get it.

Paul McCartney was smart enough to get Stevie Wonder to perform the song Ebony and Ivory with him.  Why waste such a fitting multi-racial name on a hip hop duo band that isn't made...
