I purchased these two colors too, and am surprised how difficult it is to choose. Both colors are beautiful. I liked the Graphite more than I thought I would; and, having gotten the Series 6 Apple Watch in Graphite Stainless Steel, believe them to be a fantastic match (for whatever that’s worth). I agree with
@mashinhead that in the light, the Graphite 12 Pro is just stunning (the Iron Man II reference is classic, by the way...love it). However, in certain darker environments/shadows, there can be a tinge of Midnight Green (or maybe putty), at least to my eye. I had the Midnight Green 11 Pro and by the end of the year, I was pretty tired of the color; I found I didn’t like it as much once the newness wore off. I have the same concern about the Pacific Blue. Also weighing on me is the fact that every time I’ve had an iPhone in a Black/Space Gray color, I’ve enjoyed it all year long with no regrets.
I do not use a case with my iPhone, and I think this year is by far the most difficult time I’ve had picking a color. Graphite is a safer choice, but the Pacific Blue, right now, is just fantastic.
Here are some pics I just shot of the two of them, in case this helps anybody else who is riding the fence.
