Although the 2017 grid features an array of colours, with McLaren switching back to orange, Force India to pink and Toro Rosso to a new shade of blue, red and silver to separate it from sister team Red Bull, it's often difficult to tell the drivers apart.
That's where driver numbers and helmets come in handy. However, the former are often tiny and hard to recognise from the grandstands and the television cameras, so it often comes down to knowing which driver races with which helmet.
So here's your handy guide to every driver helmet for the 2017 season (Force India's will be unveiled on Friday – expect them to be pink, in lieu of the team's new deal with BWT).
