This goes in line with RZA and his thinking since the Wu's first arrival. A good example is Raekwons album Only built for Cuban linx. It was a released as a purple tape. Not the first colored tape to be released but it became special and know as "the purple tape". It helped that it was a great album but the fact that the tape was purple became a legend within itself in hip hop. The Old Dirty Bastard album became known for having his real welfare card on the cover of his album. RZA has pulled a lot of stunts and this seems to be his biggest and most interesting one.
