Verstappen, who shared the victories with Australian Daniel Ricciardo last season, has a new team-mate for 2019 in Frenchman Pierre Gasly.
But it is understood that the former world champions will revert to their normal colours in time for the season-opening race in Melbourne on March 17.
"What I'm most looking forward to is starting the season and seeing how the whole team is operating together with Honda and how the engine is performing together with the chassis", said Verstappen ahead of the initial limited mileage filming day.
And in 2015, Red Bull's winter look was even more radical, the team initially running their new auto on track in a camouflage livery in a bid to hide its aerodynamic secrets.
The Honda-powered RB15 turned its first laps during a shakedown at Silverstone on Wednesday.
Gasly joins incumbent and five-time race victor Max Verstappen, under contract with Red Bull through 2020. "I really want to feel how it upshifts, downshifts, how the drivability is, how much power there is".
Verstappen has won five races in the two and a half years he's spent at Red Bull Racing.
"We are expecting a lot from Honda and are positive, but it will not be ideal from race one. At the moment, I am of course very optimistic, but also realistic and I think time will tell how we are going to perform". Now we can go testing properly, we'll see what we can get out of that and we'll be able to understand the vehicle and the engine a bit better.
What's changing on the Formula 1 2019 cars? You fight against teams like Ferrari, Mercedes, Renault and when you start a new partnership, it always takes time before things run super smoothly and in the most efficient way. For sure there will be moments where as a team we'll make mistakes or it's maybe not going as we want it to.
