Pssst! Hey Apple, I know you always release new color variations of the iPhone some time in Q1 of the following year, no?
Want to boost sales to the stratosphere?
Listen to me: iPhone 15 Pro (Max),
Rose Gold Titanium.
Refer to the iPhone 6S that was released many years ago. That is a shade that will work super well with the titanium alloy.
Getting the proper shade will be important, requires a bit of trial and error. Start planning
now.
And as for the non-Pro iPhone 15: my choice for a new color is orange. A pastel pale orange color, similar to the non-black colors that have been released.
