This is just a polychromatic version of that checker shadow illusion, right? http://en.wikipedia.org/wiki/Checker_shadow_illusion [[Special:Contributions/108.162.231.38|108.162.231.38]] 10:12, 27 February 2015 (UTC) | This is just a polychromatic version of that checker shadow illusion, right? http://en.wikipedia.org/wiki/Checker_shadow_illusion [[Special:Contributions/108.162.231.38|108.162.231.38]] 10:12, 27 February 2015 (UTC) | ||
:That's what I thought too. But it looks the same (doesn't it?) and is the same (that, thankfully is non-subjective and verifiable with as little as MSPaint), so I'm at loss as to why this deserves a comic.

− | : This is a common optical illusion (at least I've seen this many times) - most peoples eyes perform a white balance adjustment automatically which affects the perceived colours. If your eyes don't do this then you will do well in the paint colour matching business. http://www.moillusions.com/hue-optical-illusion/ I apologise for the jarring colours in the link. | + | : This is a common optical illusion (at least I've seen this many times) - most peoples eyes perform a white balance adjustment automatically which affects the perceived colours.

:Here's a particularly good demonstration of the underlying "color perception" illusion (i.e. the Checker-Shadow illusion referred to above): https://www.youtube.com/watch?v=z9Sen1HTu5o [[User:Arcanechili|Arcanechili]] ([[User talk:Arcanechili|talk]]) 15:45, 27 February 2015 (UTC) | :Here's a particularly good demonstration of the underlying "color perception" illusion (i.e. the Checker-Shadow illusion referred to above): https://www.youtube.com/watch?v=z9Sen1HTu5o [[User:Arcanechili|Arcanechili]] ([[User talk:Arcanechili|talk]]) 15:45, 27 February 2015 (UTC) | ||

− | + | The comic is a reference to the debate around the coloration of [http://amd.c.yimg.jp/amd/20150227-00000070-zdn_n-000-2-view.jpg this dress]. The band in the middle of the image shows some of the material of the dress. To some people, including me, the dress is obviously, unquestionably black and blue. But to others, including my wife, it's obviously, unquestionably, black and gold. | |
− | + | :And to others it's apparently a number of other combinations - I've seen claims of white/gold and blue/orange. However, surprisingly few people seem to have seen [http://www.romanoriginals.co.uk/invt/70931?colour=Royal-Blue this link] to the manufacturer's page for what appears to be the same dress; available in 4 colour combinations which according to the manufacturers' descriptions are ivory/black, scarlet/black, pink/black and royal-blue/black, with pictures available of all versions. As such I'm happy to accept the pictures doing the rounds are probably the blue/black variant (although most of the over-exposed versions I've seen appear light-blue/goldish-brown to me. | |

Our eyes are too efficient, which makes this illusion work. In dim light we dilate our eyes, so an enclosed room with one lamp seems bright, though it is a cave compared to the outdoors. If the bulb in our lamp is of a warm tone, our eyes adjust so we believe we see colours as though in daylight. I think that's what's happening in the dress illusion -- we are trying to allow for perceived lighting conditions in the photo -- so the actual illusion is in our guess as to what those light conditions actually are. And finally an artist quote: "I can paint you the skin of Venus with mud, provided you let me surround it as I will." - Eugene Delacroix [[Special:Contributions/108.162.242.84|108.162.242.84]] 13:28, 27 February 2015 (UTC) | Our eyes are too efficient, which makes this illusion work.

We can then get the actual optical illusion after all that. But as we have seen with good photos of the actual dress in normal light, the camera got it wrong. | We can then get the actual optical illusion after all that.

Is it possible that there's a connection between this comic and [[690: Semicontrolled Demolition]]? Some discussions I've seen about this topic involve the choice between white/gold and blue/black, so Randall coloured his dress gold/blue. --[[Special:Contributions/108.162.216.122|108.162.216.122]] 16:20, 27 February 2015 (UTC) | Is it possible that there's a connection between this comic and [[690: Semicontrolled Demolition]]?
