Hamilton is entering the final two races of his Mercedes career, following a highly successful 12 seasons that have yielded six drivers' championships and eight constructors' titles.
Russell is also boasting a sleek white helmet in Qatar in what is a new experience for the 26-year-old, racing in white with the Brackley-based outfit, but not for his esteemed team-mate.
Hamilton will have good memories of the white Mercedes race suits, winning championships in 2014, 2015, 2017, 2018 and 2019 in white, although he did miss out on the 2016 title to his team-mate Nico Rosberg.
