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).

      It’s also affected by one’s glasses, whether you’re nearsighted, farsighted, or just don’t wear glasses. The refraction from my nearsighted lenses makes the effect notably stronger, with the blue appearing behind the red.

      If I had to spot a guess, the effect is probably reversed with farsighted glasses, but I dunno. 🤷

        Indeed with myopia glasses, I see the red in front like being out of the screen and feeling I can grab it
