Good photos! Appreciate your posting them.
They show off nicely the difference between Silver and Starlight. In many lighting conditions in other photos, they look much the same — that is, when not next to each other. Side-by-side shows the contrast well.
That Rose Gold, on the other hand, is strikingly different. I saw one in person the other day and was staggered by how dramatic, bold, vibrant, and obtrusive the color is! (A negative for some, a positive for others.)
The photos are also helpful in showing the difference in thickness of the different laptops (especially the first photo).
Finally, what's interesting is how similar their footprints are! The 15” really doesn't look that much bigger, at all, yet in real life it has a noticeably bigger display.
