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

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.

I've definitely seen it when the colours are in focus/sharpness the same, e.g. with red words on my phone screen standing out in front of the rest.
