We color football: a reversible mosaic for El Clásico

This Sunday, some 26 years after the first mosaic was ever displayed for an El Clásico, the time-honored tradition will have a new twist — it will be reversible.

Moments before kickoff of the first clash of the season between arch rivals FC Barcelona and Real Madrid, around 90,000 oversized cards will create an image in which the words “WE COLOR FOOTBALL” will stand out in giant, yellow capital letters.

But that’s just the beginning, as the monochrome blue background surrounding the slogan will then make those very words ring true, by turning into a colorful image as the Barça Anthem is played. In order to make it all happen, the fans will have to turn their cards around in unison, revealing the traditional colors of Barça and the Catalan flag, known as La Senyera. The slogan will be the only part of the mosaic that remains unchanged.
