I guess so far as the titanium itself is concerned , a new material for the iPhone ,and a material that Apple has only had two colours for before even for the Apple Watches that had it (I think there were titanium upgrade options for the Watch series 6 and 7 long before the Watch Ultra came along) silver and space black , it will be interesting to see how the titanium actually looks in the flesh in these 4 new colours.
I presume all 4 will be anodised to achieve their particular color ,but which would be closest to the color of titanium ? Silver rather than grey ?
The guy from Zollotech suggested Titan grey would be similar to titanium.
I’m tempted to use the 15 Pro without a case so I would I want to get the most “scratch friendly” color.
