I've always really liked this explanation image you can find on Wikipedia page for it. Essentially, people who see white and gold are mistaking the lighting to be cold and blue-tinted, rather than warm and yellow-tinted.

The portions inside the boxes are the exact same colors, you can easily check this with a color picker.

As in using the colour picker on the image and finding the corresponding code? That's actually an explanation that I can get behind. Classic example of trust your instrument.

I see the dress as gold and white, no matter ehow hard I try to see the other side of the coin.

Nope. Color cannot be measured, it is created in the brain. Pickers show pixel values (stimulus) and often don't correlate to the experienced color.

[-] Track_Shovel@slrpnk.net 0 points 1 month ago

But you could use one I think, and then have that colour isolated and then dump it somewhere

[-] MrSmith@lemmy.world -1 points 1 month ago

You cannot measure perception with a color picker. Eyes + brain is not a measurement instrument.

Just like you cannot measure amount of salt used in a dish with your tongue.

Ah, so white and gold folks are, indeed, mistaken.

Thanks!

[-] MrSmith@lemmy.world 1 points 1 month ago

Incorrect. It is impossible to deduce the "real" color from the photo, both sets are true.

The photo is simply bistable.

You can argue that "the real dress bla bla bla", but nobody's looking at the real dress and everyone's looking at the photo.

This has been known for almost as long as the picture has been around. Still doesn't allow me to see it.

I don't understand this, can you explain it?

In the left I see a black and blue dress with a yellow box. The dress inside the box is still black and blue (with yellow tint).

In the right side I see a white and gold dress with a blue. box. Inside the box the dress is white and gold, with a blue tint.

What am i supposed to see here? What is this telling me?

The dress inside the [left] box is still black and blue (with yellow tint). Inside the [right] box the dress is white and gold, with a blue tint.

The black and yellow colors inside the boxes are actually the exact same color, and the same goes for the blue and white colors inside the boxes (which is what the seamless bars connecting them is there to demonstrate). But they look completely different, right? The picture is showing us two different ways the exact same colors can be interpreted differently depending on the context surrounding it.

If you go to my profile and look at my comment before this one, I posted two slightly edited versions of the image that better show how they're the exact same color.

The way this connects to the original image of the dress, is that some people see a gold and white dress because they think the dress is in blue-tinted lighting, as though they were standing in shade. People who see an overexposed image with a bright yellow tint, on the other hand, will likely see a blue and black dress. I couldn't tell you why it happens, but it's the way our brains perceive the lighting that's doing it.

If theyre the same color, why can i see the black outlines way clearer in the yellow dress w/ blue tint side ?

[-] Nelots@lemmy.zip 2 points 1 month ago* (last edited 1 month ago)

That would be because the outlines themselves are not the same colors, just the blue/white and black/yellow sections. Here's an image I quickly edited with the outlines and skin removed, so you can see just how much an effect they have on the image. Both dresses still look normal, but they no longer look like completely different colors when compared together this way.

(edit): And here's the same image with the outer boxes removed, to show how much the lighting is affecting things, where one of the dresses just looks completely wrong to me now.

I feel so dumb, you did such good work on this and… OK maybe I’ll just take another look in the morning and it’ll make sense

[-] Sc00ter@lemmy.zip 1 points 1 month ago

I never understood this concept until you made the outlines the same. That's the tip i needed to get over the edge. Thanks!

[-] parody@lemmings.world 1 points 1 month ago

lol I prob need those images described cuz for some reason…. I don’t even really know what I’m looking at heh… I’m not this dumb on other topics

[-] Nelots@lemmy.zip 1 points 1 month ago* (last edited 1 month ago)

The two boxes are meant to be different types of lighting. The box on the left is a warmer, yellow lighting while the box on the right is a colder, blue lighting, which you can tell from its effect on the grey background. The portions of the dresses inside of this "lighting" are the exact same colors, which I tried to help demonstrate with the second picture. The portions of the dresses outside of the "lighting" represent their real color without any lighting affecting them.

The point of the image is just to show how two different colored dresses could look exactly the same depending on the lighting. At the same time, the real dress from the original image is seen as different colors by different people because brains are weird and they interpret the lighting differently.

Some people see a gold and white dress in a blue-tinted light like they're in the shade, while others see a black and blue dress that is overexposed by a bright yellow-tinted light.

[-] chunes@lemmy.world 0 points 1 month ago

But the dress in the photo looks like it's in the shadow so it's a fair assumption that the lighting would be blue-tinted.

[-] SnowmenMelt@lemmy.world 1 points 1 month ago

How does it look like it's in a shadow? The rest of the photo is over exposed like in bright lights so it's safe to assume that the dress is over exposed too.
