I'm not getting a new iPhone this year, but I think they made a big mistake by not making a purple model. I could see that selling HUGE with girls/women. They probably should've done purple over coral or yellow, to be honest (if they only wanted to do 5 color options).
This reminds me of the iPhone 5C launch. Everyone was super hyped about the new colors. But as time went by, those bright colors ended up looking tacky and were more difficult to resell. And the worst part was that because of the color, a lot of people were instantly associated with a "budget" phone.
I'll probably choose the black because, unlike space gray, it's all black, which we haven't seen since the iPhone 7. It's always the safest bet.
