It’s the dress that’s dividing the internet — and the bmag office. Please, help us — what colour is this goddamn dress?

To some people, it’s white and gold. To others, it’s blue and black. There are even some people (raises hand) who thought the dress was white and gold, but now can’t see anything other than blue and black.


Seriously, what colour is this dress?

Seriously, what colour is this dress?

Ask five people in your office and you’ll get at least two different answers.

I’m… I’m really scared, you guys. Hold me?

What colours do you see, damn it?

What colours do you see?

UPDATE: OK, so now it turns out the dress is available in two colours.

That doesn’t solve anything, though — how are we all seeing different colours in the original image? What is going on? Is everyone who looks upon the cursed dress doomed to spend the rest of their life questioning their existence, and everything they thought they believed in?

This might explain things:

Are you satisfied with that explanation? Because I kind of still feel like the world is never going to be the same again…

UPDATE: Here’s another explanation, via Reddit user TechAdams:

“This is an optical illusion.

“I see blue and gold, but then again, I’m trained in color correction and color science, and then confirmed my observations using a digital color measurement of their values (Gold, btw, is simply iridescent yellow-brown). The lighter areas have digital values emphasizing blue, while the golder darker areas have digital values emphasizing negative blue. In fact, if you invert the image, you’ll get a pretty close switching of the colors, meaning they’re off by about the same amount.

“There are a couple of effects going on to create the optical illusion. First, is expectation bias: you’re cued to expect one of white & gold or blue & black, so that’s more likely what you’ll see with the illusion, rather than the true ‘colors’ of blue and gold.

“Second, you have the native internal calibration system of the human visual system. Essentially, if you focus on the blue as white, your brain “calibrates” to the extra blue, and blue calibrates for the rest of the image, pulling even more blue out of your perception of the gold. You end up seeing white & gold. Conversely, if you focus on the gold, or negative blue, your brain adds blue black into everything, making the gold appear neutral, simply darkening the brighter blue gown, making you see blue and black (darkening).

“This effect is caused by our blue-yellow light calibration system. Daylight, for instance, has a blue bias, while incandescent interior lights have a yellow bias. Our visual system calibrates to each one as we change location so that we see colors as “normal” under each set of lighting conditions, or color temperature. This is an optical illusion that tricks the eye as the brain tries to force one into one color or the other.”
