For all generations other than the iPhone X🆂 I’ve gotten the “black” option, but I really never cared for the Pro’s variant of Space Grey/Graphite. It looks brownish.
I was all set to get Pacific Blue and even preordered it, but after seeing hands on videos I promptly cancelled and went to Silver - even at the cost of an extra shipping week.
I shyed away from Silver after the X🆂 because of how easily it scratched (compared to my Space Grey model which is nearly flawless). The fact that even the Silver is supposed to have some kind of coating gives me hope.
