It may be sterotypical, but the partnership is Black man as bossman, his right hand and parter is an Irish white guy, the other business associates are of either Latin descent or Black as well, and the DEA is all shades but black (so far).

Women are good looking, and there is lots of sex and nudity (it is a Starz show).
I'm gonna guess the club **** is the part that reminds you of Arrow? but let me just tell you that this show is absolutely nothing like Arrow from a story perspective.
