No renders, but here’s my preferences.
Ferrari: all red, black wings, tricolore on the airbox
Red Bull: no purple, no Red Bull written on the sidepods, silver from the cans incorporated more.
Mercedes: lose the black on the engine cover and have Petronas green on the endplates as well as the sidepods
Williams: martini colours to be extended to cover some of the sidepod and more of the side of the cockpit
Force India: more green and orange, lose the silver
Renault: Yellow with black and white details.
Toro Rosso: less red and more gold, a navy and gold car with no red apart from the hand painted Bull please.
Sauber: I like the blue and yellow, but I would have all white wings and more yellow on the airbox and engine cover
Mclaren: white car, rocket red swooshes etc like the old Vodafone chrome livery but in white.
Manor: fully black car with red and white sponsors and minor detailing
Haas: grey, red and white car, like a cross between McLaren and Manor from last season
