Since the OBC, with the exception of swings and understudies, haven't the races of the characters pretty rigidly followed the same format.
Mark, Roger and Maureen - Caucasian
Benny, Joanna and Collins - African-American
Mimi and Angel - Either Hispanic or African-American
There's no variation from this, is there?
