I always thought the rainbow was a nod to the One Step version of Polaroid&#x27;s SX-70. It had a little rainbow strip that came down from the lens. Now its a gradient? Meh.<p>Also looks like we&#x27;re going back to extreme rounded corners again? Square is out? Heh.<p>On a positive note, I do like the white and grey tone of the app itself. Cleaner and more relaxing than the blue&#x2F;black tones.
