The Brazil players received a surprise after arriving at the team hotel in Los Cardales, 60 km from Buenos Aires, late last night: a striking yet atypical black jersey, decorated by a single, horizontal yellow stripe.
The shirt is not registered for use in official matches, even though its markings are akin to those of the country's usual canary-yellow top and second-choice blue one. However, the players will sport the jersey during press conferences and leisure time at the Copa America.
A shock defeat by Uruguay on home soil in the 1950 World Cup final prompted Brazil to abandon their all-white kit, which native fans believed was unpatriotic given that did not correspond with the colours of the Brazilian flag: yellow, green, blue and white.
So, in 1953, a competition was launched to design a kit which incorporated those colours. Aldyr Garcia Schlee, then just 19, emerged the winner of the 301 entrants and his model of canary-yellow shirts with green finishing touches, blue shorts and white socks has since remained a hallmark of the Brazilian national team.
Central to this was, perhaps, the fact that four-and-a-half years after Schlee's uniform was adopted, another teenager, a certain Pele, inspired the South Americans to World Cup glory, though they did wear blue jerseys in the final against hosts Sweden.
In 1996, Nike paid a world-record fee to assume sponsorship of the kit.
Brazil will kick off their Copa America campaign against Venezuela on July 3, before facing Paraguay on July 9 and Ecuador four days later in Group B.
Brazil have won four of the last five editions of the Copa America, though only eight overall – six shy of joint-record champions Argentina and Uruguay.
