good. he should stay with the red helmet. it's HIS red helmet, it has come to define him.
The livery of the car should be the team, and the helmet should be personal to the driver.
That's how I think it should be anyway.
and yes I know he had benneton colors before he switched to Ferrari colors, but it's completely up to him... I'd guess he considers the red helmet lucky now, just like how he wanted the numbers changed.
