Sebastian Vettel will sport a modified helmet livery for the 2009 season.
The 21-year-old German, who has switched to Red Bull from the energy drink company's junior team Toro Rosso, revealed the tweaked colours at the launch of the new RB5 before debuting the car at Jerez on Monday.
2008 Monza winner Vettel's new helmet retains its basic design in the Red Bull-tin colours of chrome and blue, but now features personalised flashes of yellows, purples and pinks.
He told reporters on Monday that his target for this year is to deliver Red Bull Technology's second win.
"Obviously it's not correct to say I am going to win the world championship, I prefer to stay on the ground and work hard," he said.
