iPhone 15 lineup to come in new colors, non-Pro models get frosted backs
According to a Chinese tipster (post has been deleted since), the regular iPhone 15 and 15 Plus will be getting frosted back finish, just like the Pro versions in the current generation. As of now, you can tell by the back finish whether the handset is a Pro or a non-Pro model.
Reportedly, the Pro models will incorporate titanium frame with curved glass edges and an additional Action button on the side frame that should still let you tell the different iPhone tiers apart.
iPhone 14 Pro Max in Deep PurpleThe report also mentions new colors. The regular iPhones will see a new cyan and green blend that would resemble the Mint Green option that came with the iPhone 12. The iPhone 15 Pros, on the other hand, are rumored to get a new dark red colorway. This one could replace the Deep Purple on the current 14 generation.
