Ogilvy's clue campaign puts all on red (and black)

To test whether its consumers know the difference between an original Coke and the brand's Coke Zero sugar free drink, Ogilvy & Mather Paris recently executed an entertaining live show of performances.

Having purchased what they thought was a classic Coke can from a public vending machine, a series of red and black-themed activities are then performed in the video as the consumers walk off supping their beverages.

The drinkers soon realise that what they've actually consumed is a Coke Zero, as a nearby team activates black Coke Zero packaging to appear on their cans.

Ogilvy Paris Digital Lab created the technology for the campaign and Chris Garbutt, executive creative director at the agency says: "Zero Clue borrows from all the makings of a traditional taste test but does it using the technologies we're enabled by to really push the creative approach to sheer consumer brand participation."
