Using Colombia’s flag and its tri-color yellow, blue and red hues, McCann created blood bags of yellow and blue on which a red stripe appears as blood is collected.The #AmarilloAzulyYo (#YellowBlueAndI) campaign from McCann Colombia was launched in October 2016 to coincide with the peace agreement signed by the Government of Colombia and the guerilla group FARC. Because the country was coming together as a nation, the ad agency used the colors of the national flag to bring Colombia’s citizens together around an important cause, that affects all of its citizens: blood donations.Colombia’s red stripe in the national flag symbolizes the bloodshed in all battles fought by the nation, and the #AmarilloAzulyYo campaign, sponsored by Marca País, used the colors of the flag to remind everyone that blood can save lives.The #AmarilloAzulyYo campaign lit up Colpatria, the highest tower of Bogotá’s financial district, eliminating the red stripe and asking Colombians to help refill the red color of their national flag with their collective donations of life-saving blood. As donations mounted, the colorless stripe slowly filled with red light.The campaign gained support across social media, the press and among media influencers, helping to drive volunteers to 15 different Colombian cities with blood donation centers organized by the Red Cross. Blood bags were created just for the effort; the bags were designed with the blue and yellow colors and a colorless stripe that turned red as the volunteer gave blood.The campaign reached more than 27 million people across social media channels and earned media. Within 72 hours of campaign launch, the blood donation rate rose 14%. In total, more than six thousand patients received blood from the campaign.CreditsCCO: Samuel EstradaCreative Directors: Alejandro Bermudez/ Reini FariasCopywriter: Ricardo RojasDirector de Arte: Rafael Montoya/ Julian Roldan/Luis Lopez/Jonnathan OlmosProduction Company: Direktor Films / BogotáProduction Company: Colombo Films / BogotáPost production Company: Bogotá Post / BogotáClient approval: Juan Sebastian Palisa
