Perhaps I am wrong, but my sense of the reported differences in the perceived color of the dress are simply due to differing viewing conditions. I have to believe that any _major_ individual difference in the perception of the dress occurring under the same viewing conditions has to be due to some type of color deficiency on the part of some of the viewers or perhaps some unusual viewing effect, such as the washed out picture of side-viewing vs the crisper picture of front-viewing of older, large-screen rear projection TVs of the 1990s. I thought that Land's Mondrian demonstration posted by Chris Green is right on the money in terms of an explanation. BTW, Land's Wikipedia bio is worth a read: http://en.wikipedia.org/wiki/Edwin_H._Land.
BTW, Mike, it's interesting that we have Gilchrist in common. I also took a couple of courses from him while at Rutgers-Newark and also had the privilege of viewing a number of his lightness constancy displays, including a miniature version of the small room display from his Science article that Debra posted; a most convincing demonstration. Gilchrist was also a member of my dissertation committee and was mentor of Fred Bonato who, I am happy to report, was elected as EPA president this year. Thanks to those of you who voted for him.

All of the offered solutions fail to appreciate an important point which is why there is so much discussion about this on social media: Why is it that two people viewing the dress under the same conditions perceive the dress as having different colors? One needs to explain why there are individual differences not that one can see different colors under different conditions. Still looking for llamas. -Mike Palij New York University m...@nyu.edu P.S. Alan Gilchrist was on the faculty at Stony Brook when I was a graduate student there and I took a perception seminar with him. I'm waiting for my Stony Brook fellow grad student Hugh Foley to chime in. ----------- Original Message ----------- On Fri, 27 Feb 2015 07:43:03 -0800, Christopher Green wrote: Edwin Land explained it to us oh so long ago: https://www.youtube.com/watch?v=3DiCvHiDWiY ...............
