One of the streetwear companies that was birthed out of the movement Cross Colours created was the eponymous brand from Karl Kani. Kani's designs were seen on the likes of Tupac, Notorious B.I.G., Diddy, and Dr. Dre, but his brand received a lot of help along the way.

When Kani first flew out from New York to Los Angeles he paid a worker at one of the factories that manufactured Guess to show him the local denim suppliers so that he could get started. Cross Colors' Carl Jones also took Kani under his wing after they met in the middle of one of the brand's fashion shows.

Kani also got a very crucial co-sign when Tupac agreed to model in Kani's ads for free. The designer says that 'Pac wore his clothing before they knew one another, and when he finally got the chance to meet the rapper he asked him how much money it would take for him to star in a Karl Kani ad. "I ain't going to charge you; you're black," Tupac said, according to Kani. "I don't charge my people for nothing." The rapper kept his promise and ended up shooting for Kani just two weeks later. Kani says those ads were part of the reason Kani gained international stardom because "they worshipped [Tupac] like a God overseas and in Europe."
