Either way, I do appreciate you posting this, Kalila. It's been bugging me and many of my friends all day.
It does go to show that what the human eye sees and what the camera lens sees are somewhat different. I perform several times a year in a tuxedo. Mine is cheap polyester, whereas some of my fellow performers have more expensive wool coats. When we have our cast party and view the film of the show, it's very easy to tell whose tux is which material because the polyester appears to be quite distinctly red. Not fire-engine red, more of a deep port wine sort of color. And the wool is basically the black that the coats appear to be in real life.
I still can't fathom how badly one can screw up the exposure to drag an apparently black material all the way to a brownish-gold shade, though. That's some hardcore photography fail.

Actually people with personality disorders do change. Or more simply bipolar people. If a defect can cause it, then why shouldn't that.

If you're going to quote yourself pointlessly, how about you explain to the world why incandescent bulbs give off yellow light.
And then when you realize why that's a ridiculously stupid reason for them doing so, simultaneously realize why we prefer light that's closer to white.

yeah idk im not understanding this myself. guess some people have some very badly tuned screens or they need an eye examination. the original picture, i.e. the first one posted in the thread, very clearly looks black with blue. unless you've never handled a cellphone camera before, you'd be able to very easily recognize via the grainyness and extremely whitewashed background that the photo is washed out like crazy due to a bad camera or bad autofocus that seems to have focused on the light coming from the upper right of the photo.
when you take that into account, it's very, very evident that the dress is black and blue. the only part that could be perceived as gold is the upper throat/breast hem and none of it looks anywhere close to white.

D and I are looking at the exact same screen, he sees a blue dress with black lace, I see a white dress with gold lace.
we both have perfect vision.

I've literally watched this image change colors on me by seeing a better photograph of the dress in question taken in proper lighting, but prior to that, my brain appears to see what the pixels are instead of adjusting them.

A simple IQ test would show who sees what colors.
It's Blatantly obvious blue and black.

Either way the dress isn't made of magical chameleon skin, so there is actually someone who is right and someone who is wrong on this topic. Whether or not those in wrong are victim of an optical illusion or whatever.

what im saying is that once you recognize that the photo is washed out/whitewashed, using the RGB of the toxic image is completely void, since the true colors are far darker than the ones in the picture. you don't have to be a photography major to figure it out either. you can't make a darker gold or a darker white when you start reintroducing color into the image.

When I look at it, particularly the heavily washed out version of the photo, it's like the over exposure is another layer on top of the actual color. I kind of wonder if the people seeing white and gold do not see layers or a veil, veneer type thing.

So.. the RGB value of the pixels on the screen, of an image on the computer that is simply data with color values, suddenly has no value because you know why the image looks the way it does.
That's all fine, but the fact remains when two people, who have no vision issues, or color blindness, are standing right next to each other, looking at the same image, they perceive the colors differently.
This isn't about why the image looks bad, or if you think the dress looks good or not, or if you think its is just a bunch of internet garbage floating around getting attention.

A simple IQ test would also tell you, that regardless of IQ, people of the same intelligence level can perceive the same information, be it physical, visual, or otherwise, quite differently.
Considering this has been touched on in several academic papers.
Which, objectively speaking, makes it appear that you are projecting your own idea of what intellectual levels are able to perceive, even though *you* are trying to convey that only smart people see it as black and blue, and idiots perceive it as something other than what is presented.

Intelligence is actually made up of many different kind of intelligences.
You can be linguistically smart, but mathematically stupid. Or have perfect coordination but terrible rhythm.
The brain is split in many areas, in some you are strong, and thus intelligent, in some you are weak and stupid.
Perception is only one thing.

I know folks who are really into photography who lose their ***over Instagram filters and such, but Joe Average who only knows how to use the Crop function on his digital camera is not worried about that. We've all seen photos where someone's skin becomes unusually sallow or ruddy, but it's fairly atypical to see colors shift as badly as it has in this one, so there's no good reason to assume, as Joe Average, that the photograph is non-representative.
I still see the black bits as a brown-gold color, too, which may or may not be related to the way my specific retina chooses to compensate. But I saw the pixels first, then the colors started shifting after I got neck-deep in the debate.

In this picture I can see blue with black on the left, white with gold on the right. The picture on the right, obviously, has a been altered, leading me to believe the dress is blue and black and not very pretty in those colors. Purple with black would be better.
I've also seen a version of the same dress in white with black.

Purple with black would be better. I'm fond of cerulean, personally.
What I wouldn't want is a dress built around lots of horizontal layers like this (assuming I was the kind of person to wear a dress).

Mine is dark blond and, now you bring it up, I guess I operate from what would suit my coloring, even when talking about opposite sex clothing. Reds look terrible on my skin, for instance.

im not arguing the initial perception issue, rather the issue of those who vehemently declare the dress as gold/white despite there being obvious photographic evidence to the contrary

I'm not specifically citing anyone in this thread
Before I begin, let me apologize for the long length/spacing of the topic. This is on purpose.
I thought this was silly, I mean... I see gold and white of course (well, really I see gold and blue), but D sees blue with black. In the past we've had discussions about what a color is on FFXIAH concerning certain game icons, so I thought this might be a bit fun to try.
Let me know what you think. Do you see a Black/Blue dress? A Gold/White? or a Gold/Blue?
So... this is a silly thing going around the internet, and now news stations. Here is the picture:
What color is the dress?
This is the question that has made everyone stupid crazy, and fighting with each other in some cases.
Before you scroll down to the breakdown of what color the dress really is, I want you to take a good look at the above, and decide what you think. Is this a white dress with gold lace, or a blue dress with black lace? or... a blue dress with gold lace (this is what I see).
So....
The person who took this photo, also bought the dress for a wedding.
http://www.amazon.co.uk/gp/product/B00SJEUCWU/ref=as_li_tl?ie=UTF8&camp=1634&creative=19450&creativeASIN=B00SJEUCWU&linkCode=as2&tag=bithedress-21&linkId=LIATY5TENJ7ORHXX
and here she is wearing it:
So, why does the photo at the wedding look different than the original photo taken that is making everyone argue whether or not the dress is white/gold, blue/gold, or blue/black?
Shadows and strong light behind it screwing with the camera. Cameras are not the same as eyes. The camera was overexposed.
What matters is whether or not you perceive the photo as overexposed in general or as having a deep shadow cast over the dress. Your brain will automatically correct for whichever one you believe, and you'll see either white/gold or blue/black.
So, what are the real colors of the photo? Is it really blue on black?
Let's pull out the RBG values...
There really isn't any black here, not a single pixel is black. The reason why some people don't see gold/white or gold/blue is because of how our brains work. Saying it again: "What matters is whether or not you perceive the photo as overexposed in general or as having a deep shadow cast over the dress. Your brain will automatically correct for whichever one you believe, and you'll see either white/gold or blue/black."
Even if you invert the photo (right side), it will not change whether you see a gold/white or black/blue dress.
Let's take the original amazon photo:
and let's replicate the overexposed shot ( white dress with gold lace. Cranking up the exposure, crushing the shadows, and increased the color temp will produce this:
Now, there is no trickery here. This is a what people see the white dress with gold lace as, and I don't think anyone can argue that. Otherwise... maybe it's your monitor...
This is what people see the original photo as the blue dress with black trim.
Now, why do our eyes work like this?
It's a matter of how your mind interprets the lighting. A white-and-gold dress in cool lighting/shadow could have produced that photo, as could a black-and-blue dress in warm yellow lighting. Your mind determines the colors of the dress based on what it assumes the lighting to be like.
The left side is a blue dress with black lace, the right side is a white dress with gold lace.
Let's brake these 4 sections out and separate them a bit so our eyes can distinguish between them.
I DID NOT EDIT THE IMAGE AT ALL, EXCEPT CROPPING AND SEPARATING THE 4 SECTIONS APART. I DID NOT EDIT THE COLOR VALUES AT ALL. THE RGB VALUES BELOW EACH SECTION ARE THE REAL COLORS FOR THE STRIPES ON THE DRESS.
Closest Color Name:
Gambogeish Black

The main thing to take away here are the names of the two "golds" and the two "blues". The left gold is named "Grayish Gold" while the right is "Dark Grayish Gold", and the left blue is named "Phthalo Bluish Gray", while the right is "Grayish Phthalo Blue". They are very similar to each other, which why each of us sees the dress differently.
Let me do this with the original photo as well, but this time I'll remove the background and only show the dress itself.

I'm sorry for the long OP, but I just thought it was pretty cool. Yea, this is all because of a bad camera shot, but this sparked a color debate war on whether it was gold/white, or black/blue, and I just think that's pretty cool how the mind works.
