Red and blue are the extremes of colours we can see, and because of the change in wave length they focus at different lengths in our eye. So to focus on either colour your eye has to adjust its focal length, which gives the 3d effect. The perspective probably adds to it.
It's called chromostereopsis - http://en.wikipedia.org/wiki/Chromostereopsis http://en.wikipedia.org/wiki/Chromostereopsis
- dudus 5y agoCame here to say this, and also that I like this other page with a good explanation of the phenomenon. http://www.ritsumei.ac.jp/~akitaoka/scolor-e.html http://www.ritsumei.ac.jp/~akitaoka/scolor-e.html

- FrostKiwi 5y agoI'm jelous :[ Being stereoblind none of the examples work for me.
- frosted-flakes 5y agoThe effect is still visible when viewing them with one eye.

My undergraduate thesis in 2005 was based on his work [0], and even at that time he had a huge body of work. [0] I demonstrated exploiting various optical illusions to create depth and animation effects. I thought I was going to revolutionize game graphics on mobile devices! And then mobile devices got GPUs shortly thereafter.

Who wear glasses, either in the face or in a camera, may have noticed, a red or blue contour on some occasions. This also happens with our eyes, but it seems the brain use this to infer depth.
- ricardobeat 5y agoWhy doesn’t it work as well on a mobile phone though? Especially since an iPhone has better color reproduction than most desktop monitors.
- herpderperator 5y agoI think it may also depend on the subpixel geometry[0][1] (and pixel density) of the screen. There are a lot of ways to arrange subpixels.

- pwillia7 5y agoThis hurt my eyes more than any image I've ever looked at -- desktop monitor. Ow.
- vgel 5y agoWorked for me on my iPhone 6s+, though not as strong as OP described. Maybe LCD vs OLED?
- rkangel 5y agoIs it because you're viewing it at a different distance (phone usually closer than monitor) and therefore the focusing variation is different?
- spartanatreyu 5y agoThe strongest example I've found of Chromostereopsis that I've found: https://pbs.twimg.com/media/CeaBIWdWEAAmm4_.jpg https://pbs.twimg.com/media/CeaBIWdWEAAmm4_.jpg I have another example in my design inspiration notes that is based on a live action image: https://i.imgur.com/Tau4fHc.jpg https://i.imgur.com/Tau4fHc.jpg
