Goddam! Thank you!
That kind of explains the gold or black dress!

I can for the life of me only see it as white and gold, and I have really struggled trying to understand how others can see it as blue and black? I bet the picture you show here is a result of the research the picture of the dress initiated. It can't be a coincidence that the illusion you posted also is made with dresses.

It's such a strange thing. For most of the illusions I can trick my brain to perceive both variants. This one is clearly black and blue. I can see that the black parts isolated can appear golden in the light, but for the life of me I can't see it any other than blue. Brains are weird.

Whitebalance comes to mind. Human eyes perceive the long rectangles' tint as a base color, i.e. effectively neutral/white.

So yeah, a blue dress in a yellowish light might look the same as a yellow dress in a bluish light.

I don't understand why people are arguing about a terrible picture. The colours are blown out. So you could misinterpret them as badly lit white and gold.

I wonder how much of this depended on the differences in device screens. In 2015 there was a lot more variability in display technology, lower resolutions in general and worse color fidelity. OLED was uncommon and expensive, you probably only had an IPS display if you worked in graphic arts, and a lot of people were still using standard LCD monitors backlit with fluorescent tubes, which meant that the black depth was limited and the detail in dark regions of an image was frequently not visible on the screen.

In the drawing, the surrounding background and the hard black lines on the lighter version are probably causing that we don't compensate the light in the same way in both drawings. We are not given the same picture like it happened with the original photo.

I don't get it. Are they suppose to look similar with the filters applied? I see both dresses underneath the filter, very clearly. On the left is the same black and blue dress with a yellow filter effect, on the right is a yellow and white dress with a very clear blue filter on top.

Yeah, don't worry, you're supposed to be able to see they're different.

The majority of the image being grey is gives your brain the right context required to perceive each half is being tinted, so the perceived white balance isn't shifted around like in the original "the dress" meme.

This is more of a teardown of the "original" illusion than a demonstration.

Looking at the bridge, it becomes clear that even though you can see in the wider context that the dresses are separate colours - when compared directly under skewed/tinted white balance they become indistinguishable.

Meaning that in the original "the dress" meme, how you perceived the dress' colour depended greatly on how you perceived the tint/white balance in the surrounding areas of the photo (or how it was displayed on your device).

It was only after following elaborate instructions: change the brightness, squint, and cover up this section of the image, that I was finally able to see a white dress.

As stupid as it was, it was a pretty cool accidental worldwide psych experiment.

The original dress really was white black and blue. For some reason, I thought it was confirmed otherwise.

The point is that a black-and-blue dress, when brightly lit, will look eerily similar to a white-and-gold dress, when it's in shade.

I have a hypothesis that the dress just shows that lots more people have some weird issues with color. Not necessarily outright color blindness but moreso just general processing issues. But what do I know I'm just some asshole with photosensitivity.

Yes, but the black and blue is actually exactly the same color as the yellow and white. They're both the same color but one looks black/blue while the other looks white/yellow.

The left and right dress are exactly the same color. However, your eye makes you think the left is black/blue while the right is white/yellow. (Within the shaded area)

Apparently this is the same dress, the colour balance of the one on the left is just that fucked up.

The first couple times I saw the dress I saw it as white/gold. But after learning it was black/blue I stared at it and the colors seemed to shift in my brain. Now I can't see the white/gold for the life of me.

But if you take a color picker, you can clearly see the RGB values from the image to match white and gold.

Were arguing. This happened about 10 years ago, so keep the quality and variance of computer monitors at the time in mind. That, and the average person doesn't know what color balance/contrast is. Plenty of people don't even realize that the same image can look different on two different monitors.

I did the color picker thing too, and its result was blue and orange. Not super helpful to this particular global controversy, but was worth a shot.

IMO the color of the actual physical dress is kinda moot: photographed (poorly), digitized, and presented to the world on billions of screens with completely different settings for things like color saturation, and the color of the thing that hits our eyes is not necessarily indicative of the color of the original.

The color of the dress in the photo was not the same as the color of the photographed dress.

It was white and gold! sprints away

On 28 February 2015, Roman Originals announced that they would make a single white and gold dress for a Comic Relief charity auction.[31]

Oh man, MAJOR missed opportunity there! They sold out of the blue and black ones like overnight, they should have fast-tracked a white and gold version production to hit the shelves ASAP and enjoyed the flood of purchases.

To be fair, we’re the ones who makes the definition and therefore can make them fit our, in many cases, fragile ego. We’re only the most intelligent animal because our definition of intelligence is based on our self.

Just looked up the origonal dress pic on my pixel 8 pro. Its still white and gold to me. I've only ever seen it as black and blue (without aid) a handful of times since the day it went viral. In sure screens could influence this, but this damn thing stands as a powerful illusion on its own.

True, luckily many modern researchers are less biased. A lot of the bias is from religions, that claim that humans are special.
From modern research we now know that we are not special in many many aspects. Apart from being a bit more intelligent, we are clearly the same in more ways than we are different.

I have no idea what must be wrong with someone's eyes to call that dress white and gold. I mean it was always a stretch, the shadow/lens on top of it would have to be fucking BLUE to color it something similar.

Even then it sounds stupid to go with that stretch of it being white and gold.

My working theory is that people who saw it gold and white were exposed to lead.

I was able, very briefly and not since, to see white and gold. Otherwise, I thought they were all crazy.

I was exposed to lead and yet I only saw blue and black.
