The latest smartphones pack all manner of changes to get you to buy them. But one unsung feature upgrade is new colours. Each new phone line-up sports a new range of colours for you to pick from. It might sound like a subtle change, but it can be enough for some to upgrade their handset. I’m guilty of it, with the iPhone 14 Pro Max’s purple and 15 Pro Max’s Natural Titanium catching my eye. And the iPhone 16 is set to be no different.
