FIA head Jean Todt backs idea of 'yellow jersey' for Formula 1 halo

With the arrival of the Halo in 2018 having divided opinion, there is hope that teams will make the devices more visually appealing, either through aerodynamic tweaks or through the use of different colours.

Todt is pushing for F1 to make use of the opportunities on offer, and suggests the halo is used for improved car number visibility or even to single out the championship leader.

"There are some clever ideas," said Todt when asked by Autosport about his views on the looks of the halo.

"I heard one idea that I quite like: we should give a different colour of halo to the leader of the world championship.

"I want to see the name and the number of the cars, which we cannot see.

"So maybe it will be one opportunity to give that - even if I hear already that teams have sold the space to sponsors. So lucky them!"

In cycling's major stage races, leaders are given a different colour jersey to the other riders - with the Tour de France famously using a yellow jersey.

Todt is unmoved by the fan backlash over the halo, and says his only regret would be not pushing through with the system and there being an accident.

"Honestly, I don't care," he said.

"I do care if something will happen and I will realise that we didn't do something that we could do.

"If you see all the last severe crashes in single-seater racing, they have been around the head.

"I am sure that other bad incidents will happen, and we need to have a vision to do something beforehand."
