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).

As with all those illusion it depends on how the brain interpret things… Perhaps your brain is clever than mine to see the image how it really is

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. 🤷
