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 ...............

The internet was caught up in a frenzy yesterday -- no, I'm not referring to the llama video -- but about an optical illusion that people did not realize was an optical illusion. Indeed, it was an amazing demonstration of how unquestioning a person can be of their perception of things in the environment as well as the degree of overconfidence they have in their own judgments. To see where you fall, check out the dress at the following link and then select one of the multiple choice answers: http://swiked.tumblr.com/post/112158479910/trinititties-snacksandharts-swiked (a) The dress is red and green (b) The dress is white and gold (c) The dress is blue and black/brown (d) What dress? Now, the explanations I've seen for this phenomenon hasn't been completely satisfactory because they tend to be vague and don't use the combined trichromaticity theory-opponent process theory we all are familiar. For one source of explanation, see the story on the Wired website: http://www.wired.com/2015/02/science-one-agrees-color-dress/ and http://www.washingtonpost.com/news/morning-mix/wp/2015/02/27/the-inside-story-of-the-white-dress-blue-dress-drama-that-divided-a-nation/ A less neuroscience-ish explanation is provided here: http://sploid.gizmodo.com/this-is-the-real-color-of-that-goddamn-white-and-gold-d-1688381523 and http://sploid.gizmodo.com/this-is-the-real-color-of-that-goddamn-white-and-gold-d-1688381523 So, which of the multiple choice answers is correct? Why, (d) of course. .;-)
