Apart from cute little Fiats or whatever, which can carry pink, lime green etc quite happily...
But a grown up car: can it be a colour that's not black? Or maybe, at a pinch, very dark metallic grey?
And if it's black outside, does it have to be black inside as well?
Obviously I use the term 'has to' loosely and not in a sense that everyone will be willing to recognise. But basically, if you were buying a car, and had some input as to colour, would you go for anything that wasn't black?
