If your first thought is What is this nonsense?! just take a second to hear out Instagram's reasoning for the change."Brands, logos, and products develop deep connections and associations with people, so you don’t just want to change them for the sake of novelty," Ian Spalter, Instagram's head of design, wrote in a blog post on Medium. "But the Instagram logo and design was beginning to feel, well… not reflective of the community, and frankly we thought we could make it better."Instagram first debuted its faux leather-clad camera icon four years ago (and the app itself is five years old). Back then, all you could do on Instagram was take and share photos, painting them with a filter. Nowadays, you can share photos, videos, collages, GIF-like Boomerangs , and Hyperlapses , and you can discover all sorts of new content in its Explore tab. With all that in mind, it makes sense that Instagram would eventually want to evolve from its vintage-looking camera icon, and the company's been working on this new design for almost a year.The app did try to keep a few key aspects from its old logo: the rainbow, and the camera lens. The rainbow manifests itself in the warm gradient, while the camera lens is evident in the super minimalist camera glyph in the icon.Naturally, Instagram expanded this new colour gradient and glyph-styling to its entire suite of apps (Layout, Hyperlapse, and Boomerang). You can get more detail about how Instagram arrived at this design in the video below.In addition to the new icon, Instagram also made some design tweaks in the app itself. Gone are the blue buttons and nav bar at the top and bottom of the app. Now, those are white, so the only pops of colour come from the photos themselves (and those little orange notification icons). There are also some subtle differences between the iOS and Android app that aren't too noticeable unless you've got the two versions side-by-side.
