Green branding from title partner Mission Winnow also features on the engine cover.
The team enters the 2021 season with a revised driver line-up of Charles Leclerc and Carlos Sainz.
Leclerc shaded Sebastian Vettel during their first season as team-mates in 2019 before spearheading Ferrari’s charge during its troubled 2020 campaign.
Sainz joins following prior spells at Toro Rosso, Renault and McLaren.
Ferrari has focused its development tokens on the rear-end of the SF21, recognising it as a key weakness last year, and has introduced a new power unit, transmission and suspension, while the nose section has also undergone a reprofiling.
It means all 10 teams have displayed their 2021 Formula 1 machines.
The SF21 is set to run for the first time during a filming day at the Bahrain International Circuit on Thursday, ahead of the start of pre-season testing on Friday.
