The green iPhone 11 is a cute option, much lighter than the iPhone 11 Pro and Pro Max's Midnight Green.
This pastel color will show scuffs easily, so you'll probably want a case, or you'll need to be extra careful. This minty color says that you'll do just about anything for the aesthetic, and your Instagram theme is probably cultivated like it's your job.
Green draws your attention, but this shade is light enough to go under the radar, too.
