Talk:1492: Dress Color
What is the illusion supposed to be? The colors of the dress look a bit darker with the light background, but not very much. Is that the illusion? --220.127.116.11 07:07, 27 February 2015 (UTC)
- Agree. To me, it looks like it's definitely light blue (maybe "cornflower"?) with pale olive stripes. "Gold" would really be a stretch. It looks like that in all lighting conditions and in both backgrounds of the strip. Did I pass some kind of color-blindness test? Or fail? 18.104.22.168 07:43, 27 February 2015 (UTC)
- This has nothing to do with color-blindness, but probably with certain arbitrary constants related to white-balance adjustment that differ brain-to-brain. Many people I know insist that even though the picture looks blue, it's a dress illuminated by a blue light, and based on this assumption their brain may essentially redden the whole picture to adjust for this light. The actual picture was taken in white light, not blue light. 22.214.171.124 07:46, 27 February 2015 (UTC)
Apparently for some people the left-hand-side's general blueishness is adjusted against by the visual system enough to make the dress look white and gold instead of blue and brown. I am not one of those people. 126.96.36.199 07:43, 27 February 2015 (UTC)
Description says left for both 188.8.131.52 08:37, 27 February 2015 (UTC)
- Now changed. (Saw it myself before I saw your comment, and just lept straight in there. Hopefully I changed the right left so that it's right and not left the wrong left whilst producing the wrong right. Alright?) 184.108.40.206 09:30, 27 February 2015 (UTC) (Also, "hello near-IP neighbour!"... The same digits, even. Creepy.)
Are they really the same colour? 'Cause to me on the blue side it looks blue and black- while on the white side it looks white and gold. Is this normal? -- FlyingPiggy (talk) (please sign your comments with ~~~~)
The figure on the right definitely has a beard. 220.127.116.11 09:38, 27 February 2015 (UTC)
I checked with ColorZilla and the RGB values are identical. From my perspective, in the one on the left the dress appears pale blue with darker brown/gold stripes, and the one on the right appears a darker blue with lighter brown/gold stripes. 18.104.22.168 10:10, 27 February 2015 (UTC)
This is just a polychromatic version of that checker shadow illusion, right? http://en.wikipedia.org/wiki/Checker_shadow_illusion 22.214.171.124 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. 126.96.36.199 10:47, 27 February 2015 (UTC)
- 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.
The comic is a reference to the debate around the coloration of 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 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 188.8.131.52 13:28, 27 February 2015 (UTC)
