Coca-Cola Uses Optical Illusion in OOH Campaign

Coca-Cola’s “You Must Love Coke” OOH push found a way to show up in football stadium ecosystems where wearing (or displaying) red can range from “not advised” to “choose-your-own-adventure.” The trick: billboards and placements that contain *zero* actual red, yet still prompt viewers to “see” Coke’s signature color anyway—because their brains do the work. It’s rolling out first across Argentina and Brazil, with a broader global expansion planned.

The creative mechanics lean on perception science—specifically color afterimage effects—using blue-toned visuals and patterns that coax the eye into generating the complementary red. In other words, Coca-Cola gets brand recognition by letting fans’ visual processing (and brand memory) fill in the missing piece. Media placement is baked into matchday behavior: supporter routes, stadium perimeters, and fan gathering points, plus social content designed to trigger the same effect on mobile screens.

From an execution standpoint, WPP Open X led the work (with VML and Grey, supported by Ogilvy and WPP Media), and the larger takeaway is less “clever illusion” and more “respect the local code, then earn attention inside it.” Design Rush also points to broader OOH tailwinds: U.S. OOH hit $9.1B in revenue in 2024, with transit formats up 10.6%. No campaign performance results yet, but the real test will be whether this culturally specific color workaround scales cleanly when football tribalism (and color taboos) change market to market.
