Pirelli has confirmed that a simplified colour coding system will be used for its tyres in Formula 1 next season.
Pirelli currently has a range of seven compounds, each with their own name and coloured sidewall, from which three are taken to each Grand Prix.
They range from the Hypersoft to the Superhard (a back-up compound not yet used at an event), and include the Ultrasoft, Supersoft, Soft, Medium and Hard.
It has led to situations whereby the Supersoft can be the hardest available compound at a Grand Prix.
From next season, Pirelli’s tyres at each event will be known as Soft, Medium and Hard.
The Soft will have a red sidewall, the Medium yellow and the Hard white.
Pirelli will still have a range of either five or six compounds, which will be coded in either letter or number form, and from which three will be chosen to be assigned as Soft, Medium and Hard for a respective event.
The specific compounds that have been assigned for each Grand Prix will be revealed prior to the respective event.
"For a bit of time we were talking about this idea, to eliminate what we call the rainbow, as we have too many colours and sometimes it's not easy for spectators to understand the difference in compounds," said Pirelli chief Mario Isola.
"After some discussion we have decided to use, I would say, the most famous three colours in our range."
The 2019 tyres will be sampled by drivers for the first time at next month's post-season test in Abu Dhabi.
The Intermediate (green) and Wet (blue) tyre designations will not be changed.
Pirelli is entering the final year of its current deal, with the company facing competition from Hankook for the 2020-23 contract.
