Haas announced their split from Rich Energy on Monday after a bizarre 11 months as often uncomfortable bedfellows.
With Rich Energy having previously attempted to annul the sponsorship, and Haas seeking £35million in damages as a result, the long-term prospects of a deal that had been due to run until 2022 have seemed shaky for some time.
The business ramifications will become clear over the coming months, but a big question remained after the announcement - what will Haas' car look like for the rest of the season?
Of course, Rich Energy's logos and branding will disappear for the Singapore GP and beyond. Having taken on Rich's black and gold colours, Haas may also have a long-term decision to make on an even greater change.
For now, though, the colour scheme will remain, so Romain Grosjean and Kevin Magnussen can pretend they're driving a Senna-era Lotus for a few more months at least.
