Juice billboard declares: "Once you go black....."

The trendy black bottle for fruit juices that taste good but are less than appetizing to look at has reached the USA. While German based True Fruits sold their black bottle with the idea of beauty on the inside, which offended some readers, USA based Juice (served here) decided to take another route.
"Once you go black..." is an expression about black men in bed and about as subtle as the movie Mandingo was. This headline isn't something that makes me think of innovative cold-pressed detox juices, but it seems sexual innuendo is part of their campaign, judging by prior "soft, semi or hard how do you take it" headline (below). Naturally there's already a Change.org petition to "take down billboard with racial undertone", because those things work so well.
