The new livery replaces the grey and red colours of Haas owner Gene Haas's company which branded the auto previously.
English entrepreneur William Storey is the face behind Rich Energy, which has teamed up with American outfit Haas for the forthcoming campaign after failing in its takeover of Force India a year ago. However, the American squad has a big bridge to cap to close down Red Bull.
However, Storey, Rich Energy's long-bearded boss, says he wants Haas to compete with energy drink giant Red Bull on and off the track in 2019.
"We are confident we will beat Red Bull in many races this year", he said.
The striking design of their new auto, reminiscent of the former Lotus F1 team's colours, was unveiled at the Royal Automobile Club in London on Thursday. We're expanding very quickly, we're taking a huge amount of business from them. Some of the biggest drinks distributors in Europe are de-listing Red Bull now.
"I really don't expect us to take a step back, I think we're going to continue to grow".

"We intend on being in Formula 1 long, long term and we believe that Haas are a dream partner for us".
"It's important that we keep progressing as a team, and this season is no different", commented Steiner. It has a brand value, F1, which I think is unprecedented in sport. "I think a lot of people have put two and two together and got five".
"We just feel we've got a better product and a better brand and we feel that there's a little bit of apathy and, dare I say, hubris in the market place".
Team principal Guenther Steiner said of the sponsorship: "Securing a title partner in Rich Energy is another milestone moment in the development of Haas F1 Team. If you have no targets you never achieve anything", he said.
"To take as big a step [in 2019] is very hard - it's going to be incredibly hard to even hold on to where we were a year ago".
Red Bull have switched to Honda engines from Renault this season, with a question mark over performance and reliability while Haas have a Ferrari power unit in the back of their auto.More news: Jason Day, Phil Mickelson among early leaders at Pebble Beach Pro
