Why Brazil wore black kits for the first time, in a friendly against Guinea
For the first time in their history the Brazil national team dumped their traditional yellow or blue kits in favour of a black kit, against Guinea.
There are few things more iconic in world football than Brazil's yellow and green shirts, which they've won a record breaking number of World Cups wearing.
Earlier this year it was announced that the five time world champions were going to break from the norm and wear a green kit for one of their summer friendlies.
On Saturday the RCDE Stadium, which normally hosts the recently relegated Espanyol, was their home for the game with African side Guinea.
The South Americans ran out 4-1 winners with in form Newcastle United star Joelinton getting the opening goal on his return to the national team.
Rodrygo scored another before half time before Sehrou Guirassy pulled one back for the Africans, only for Eder Militao and Vinicius Jr to finish the scoring in the second half.
There were no signs of green kits however with Ramon Menezes' team actually wearing all black in the first half before changing to their traditional yellow strips at the break.
It was all part of an anti-racism campaign with the team taking up the slogan, "With racism, there is no game" [Com racismo nao tem jogo.]
In a statement, Brazil football federation president Ednaldo Rodrigues said: "From the first day of my mandate, this [battle against racism] has been a priority.
"We held a seminar on this topic, and we created a working group with 60 persons who meet periodically to advance discussions and proposals.
"We are the only football federation in the world that created a mechanism that allows for points deductions for acts of racism, which is included in the federation's official competition guidelines."
The issues with racism in football have recently been brought to the fore one again with the abuse that Real Madrid star Vinicius Jr has received.
Atletico Madrid fans hung a dummy of the player in a Real kit from a bridge in Madrid earlier in the season, whilst singing racist songs.
Towards the end of the season he was abused from the stands in a game against Valencia and was sent off after reacting, though the red card was later revoked
