I see the red rings in front. I tried adding some depth cues to see if I could see it both ways - https://i.imgur.com/LsPtsRr.png

It kind of works, but for me it feels more like the blue ring now has a variable depth, with parts below and parts above the red rings, kind of like a piece of fabric draped over a bar.

I wonder how it feels for people who see blue in front?
