Fernando Alonso is running a special camouflage helmet livery on the opening day of pre-season testing at Barcelona for the upcoming 2017 Formula One season.

In a move away from his usual helmet design -- which mainly includes the colours of the Spanish flag -- Alonso is sporting a one-off black and white camouflage helmet, as he completes first duties behind the wheel of the new 'Tarocco' orange and black McLaren MCL32, before Stoffel Vandoorne takes over on Tuesday.

Both drivers have already had a brief taste of driving McLaren's 2017 challenger on-track at the Circuit de Catalunya during a filming day on Sunday, ahead the first pre-season test at Barcelona this week.

McLaren shared images of Alonso's testing helmet on Twitter.
