Pirelli has revealed the colours it will use during the 2011 F1 season to distinguish the six different types of tyre that will be available to teams.

Each tyre will carry its own distinct colouring on the Pirelli and PZero logos affixed to the sidewall. The decision to give each type of tyre its own colour will ensure that fans can easily tell which tyre is being used at any time, rather than tyres simply being marked as 'prime' or 'option' - given that different tyre combinations will be taken to different events over the course of th eyear.

The list of colours to be used in 2011 is as follows:

Wet - orange Intermediate - light blue Supersoft - red Soft - yellow Medium - white Hard - silver

Pirelli plans to offer teams a step of at least one compound between tyres at each race this season, with hard and soft tyres being taken to Australia, Malaysia and China - meaning yellow and silver marked tyres.

"We' re very excited by the prospect of returning to Formula One for the first time in 20 years, and we're aiming to be a proactive and colourful partner in Formula One," Pirelli motorsport director Paul Hembery said. "So what better way to symbolise this than a brightly coloured selection of Pirelli logos to run on the sidewalls? These will enable both live and television audiences to tell at a glance who is on what compounds, which will be vital knowledge as tyres are set to form a key part of race strategy this year."
