For the 2020 F1 season, Lewis Hamilton and the Mercedes F1 team decided to wear black overalls and even paint their cars in black in order to support anti-racism campaigns.
Hamilton even changed his helmet design and started to wear a black helmet from the start of the year with the Austrian Grand Prix.
The helmet is black and purple and has the BLM logo on the top.
