A community for sharing and discussing cool optical illusions.
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
Edited: added Wikipedia link
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.)
Yeah blue looks sunk to me too
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
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.
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.
Red and blue are on opposite side of the visible spectrum.
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
I can't do Magic Eyes either!
I think it also depends on your viewing screen
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
Not sure if it's because I just woke up, or if it's dark mode, but looks flat.
Chromostereopsis. Pretty cool. Actually works on print too but very easy to observe on displays.
Thank you!!

Hmm, for me, it depends on how close or far the screen is. When it is closer to my eyes, the blue sinks into the screen. When it is far, the blue pops out of the screen towards me.
Good catch! It was just behind for me, usually don't have phone too far back.
mmmmm not seeing it tbh
It's too early in the morning for brainfucks..
Just take my upvote 👍
If I go fullscreen I can see the reverse (blue is lower than the red). Its fairly subtle
Way to out yourself as having thick glasses haha.
I bought this from a Deviant: https://www.deviantart.com/chromostereopsis/art/Starry-Night-by-Van-Gogh-in-Chromostereopsis-756307139

Woah! This is cool!
