While this is just a static 2d image, it looks like blue is above the screen (for me, for some others it’s below, or red is above).

    Okay so what’s going on here? This is the first time I’ve seen this illusion without my glasses, though it’s stronger with.

    I see the blue further back; the red sticks out forward to me. And I’ve seen that with colours on my screen and - I think - printed colours too sometimes.

    Or is this something else, about the blue being a bit fuzzier or something? (In which case my own colour depth separation is something else.)

      I’m guessing it’s the fuzziness of the blue one (less focus), but also both red segments being wider/thicker so your brain rationalizes that blue is further away

        I’ve noticed this effect on business signs so I don’t think that’s the cause. Blue specifically seems affected, and you can notice a parallax difference too even when they’re the same distance. I assumed it had to do with my glasses bending the light differently or something.

        Blue isn’t fuzzy or blurry though. It’s just as crisp and sharp as red, digitally speaking.

        But yes, without glasses, I get the same sort of experience, where the blue gets blurry before the red.
