As Øyvind Kolås, the original creator of the ilusion noted:
The visual experiment that went along with my previous post went
viral, the one that went viral was an already lossily compressed JPEG
that has also gone through further cycles of viral degradation by
scalings and further JPEG recompressions.
He gives a higher quality version:

this is the so-called Munker illusion, similar of White's illusion.
So named after Munker H (1970): "Farbige Gitter, Abbildung auf der Netzhaut und übertragungstheoretische Beschreibung der Farbwahrnehmung" [Chromatic grids, projection to the retina, and translation theory-based description of the color perception].
In psychology books handling human ...
The human visual system (i.e. eye + brain) processes chroma (e.g red vs green) differently to luminance (i.e. light vs dark colours). In particular the brain derives fine detail and texture from luminance information, but treats chroma as a much more "broad brush" thing. This is why something like red text on a green background is so hard to read: your brain ...

The dress in real life
Yes. The original dress is black and blue. The dress has been identified and there are many professional photographs which show its colours unambiguously. See reports referenced below.
The dress in the photograph
The photograph being circulated is a very poor ...
It's quite plausible. The 'fog' which surrounded the iceberg may have been a mirage caused by super-refraction.
The British Government's 1992 MAIB report posits the presence of super-refraction as a possible explanation for why CALIFORNIAN could see TITANIC even though the two ships appear to have been beyond each other's horizons (and TITANIC could not see ...
This phenomenon is just the result of the Agent detection.
I asked two similar questions on cogsci.stackexchange which interested people might like to read:
I think it is mostly a result of "hyperactive agency detection"; this
results in "single-cause" reasoning as part of ...
I don't like to give simple direct answers, mainly because I don't think I have enough certainty to do so, but also because I prefer to offer the data that I had analyzed and then see if the other person came up with a similar conclusion.
I think the core of this tendency to anthropomorphize odd shapes of materials is grounded on the making of false-...
