Red Bull has confirmed a return to their traditional livery for 2019 as pre-season testing gets underway in Spain.

The RB15 was given a bold new look for its shakedown last week at Silverstone and it was thought, as part of their new partnership with Honda, the colour scheme may at least be tweaked.

However, the same matte design that has been in place since 2016 will once again adorn Adrian Newey's latest creation.

Max Verstappen will start the first test behind the wheel on Monday before new teammate Pierre Gasly finally gets his first chance on Tuesday in Barcelona.
