I got the Sky Blue at launch because the lighter colors felt more "airy". I returned it because it was too big for one handed operation. I was getting FOMO for black though. It just looks so sleek.
I've been using a Sage Green iPhone 17 but I missed the Air so I got one in Space Black when I saw AT&T was running a promotion ($5/mo for 36 months, no trade-in required). I needed a grip for the iPhone 17 anyway and the Air felt a lot lighter than it should plus I missed the screen size.
