Still can't vote, but mine will be what we call Artic Silver, which is basically a light blue and the 'special' colour they come in. My first choice was Titanium grey, and I think that looks the best, but my last 3 cars were ordered in a shade of dark grey, so SWMBO is happy, even though I'm not completely enamoured with it.
As for the inside, unless I'm mistaken, we have a choice of black, black, or black... Having said that I have been watching the white/off white interior with interest and may well change the colour as that is actually pretty cheap to do so, and then I can have rear heated seats for Little Miss SWMBO, as that was how I got her over the line with the Tesla, but lack of availability and also a slight lack of funds as well...
