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).
Thanks to comments, here some explanations https://en.wikipedia.org/wiki/Chromostereopsis

To me it looks like blue is under the screen
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.

Edit: oh and now I see OP also already got the link
Wait you guys are getting 3d Effekts from this?
I can’t seem to see this in any way but flat
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. 🤷
Not sure if it’s because I just woke up, or if it’s dark mode, but looks flat.
