Back to orange livery for McLaren?
Nope, they're keeping the current one. Vodafone probably wouldn't approve of an Orange livery.
the McLaren situation.
what situation exactly? Having Button you mean?
It would seem so. Amanda doesn't like Jenson.
I'm not a huge fan, that's no secret, but I honestly think that Kimi would be a better fit for McLaren and I'm not sure that it's a great move for Button either. Although, if the Brawn (edit: Mercedes now, I guess) seat is gone, then McLaren is without doubt his best chance next year.
I agree, It's difficult having two top-tier drivers in a team at the best of times, but JB and Lewis have very different styles. Jenson's going to have the double problem of trying to fit in with a new team which is well integrated with his teammate and driving a car better suited to a different style. But with Mercedes seemingly closing the door on the Brackley option, McLaren is the only viable alternative. This situation gives McLaren all the cards, they get to choose between Jenson & Kimi, neither of whom really have any other options. World Champions are not going to take cheap drives in Manor Grand Prixs or Lotuses.
Edit: All that being said about the Lewis/Jenson pairing, if McLaren can make it work - getting the car right for both of them, making JB feel at home - then they could have one of the most formidable pairings on the grid, one of the best pairings in a long time. Lewis a ruthlessly and relentlessly fast racer and Jenson a wise, methodical driver virtually guaranteed to score and very easy on the cars & tyres. They compliment eachother perfectly.
