Remember February 2015? It was a weird time. Before the world got arguably much heavier, we were all screaming at our coworkers over a single pixelated photo of a bodycon dress. Some saw royal blue and black. Others—and I’ll be honest, I was one of them—saw white and gold. It felt like a glitch in the Matrix.
That white and gold dress viral moment wasn't just a flash in the pan. It was a massive, accidental experiment in human biology.
It started on Tumblr, of all places. Caitlin McNeill, a Scottish folk singer, posted the photo after a wedding where guests couldn't agree on the color of the bride's mother's dress. Within 48 hours, it was everywhere. Kim Kardashian saw white and gold. Kanye saw blue and black. Taylor Swift was team blue. It sounds silly now, but it actually broke the internet. Literally. Servers at BuzzFeed and Tumblr were sweating.
What was actually going on with our eyes?
It’s called color constancy.
Basically, your brain is constantly trying to "subtract" the lighting from an image so you can see the "true" color of an object. Think about it. If you take a white piece of paper outside at sunset, the paper looks orange. But your brain knows it’s white, so it filters out the orange light.
With the white and gold dress viral image, the lighting was perfectly ambiguous. The photo was overexposed. The background was bright. Because of that, your brain had to make a split-second executive decision: Is this dress in a blue-tinted shadow, or is it being hit by yellow artificial light?

If your brain assumed the dress was in a shadow (which has a blue tint), it subtracted the blue. What’s left? White and gold.
If your brain assumed the dress was being hit by bright, warm light, it subtracted the gold/yellow. What’s left? Blue and black.
The neuroscientists actually got involved
This wasn't just a meme for long. Real scientists at places like NYU and MIT started published peer-reviewed papers on this. Dr. Pascal Wallisch, a neuroscientist at NYU, did a massive study with over 13,000 people. He found something wild: your "chronotype" might determine what you see.
Are you a lark? An early bird? Larks spend more time in natural daylight, which has a lot of blue in it. Their brains are trained to ignore blue. These people were way more likely to see white and gold.
Night owls, on the other hand, spend more time under artificial, yellowish light. Their brains are used to filtering out that yellow-gold hue. Unsurprisingly, they were much more likely to see the dress as it actually was: blue and black.

It’s kinda crazy to think that your sleep schedule changed how you perceived a viral photo.
Why the white and gold dress viral phenomenon happened when it did
Social media was in a specific "sweet spot" in 2015. We had the scale of global connectivity, but we hadn't yet become totally cynical about shared experiences. The dress was a rare moment of "objective" disagreement. Usually, we argue about politics or art—things that are subjective. But this was a physical object. It should have been one color.
The dress itself was made by a British company called Roman Originals. They confirmed it was blue and black. They even ended up making a one-off white and gold version for charity because the demand was so high.
The science of "The Dress" vs. "The Sneaker"
A few years later, people tried to recreate this with a sneaker (pink and white vs. grey and teal) and an audio clip (Yanny vs. Laurel). None of them hit quite as hard.
The sneaker didn't work as well because the lighting cues weren't as perfectly balanced. The white and gold dress viral image was a "perfect storm" of poor photography. The overexposure was just enough to hide the black lace's texture, making it look like a reflective gold material under certain assumptions.

What we can learn from the chaos
Honestly, the biggest takeaway isn't about fashion. It’s about humility.
We all walk around thinking we see the world exactly as it is. We think our eyes are cameras. They aren't. Our eyes are sensors, and our brain is the editor. The editor has a bias based on your past experiences, your environment, and even how much sun you got that morning.
If we can't even agree on the color of a lace dress from a wedding in Scotland, imagine how much our brains are "editing" when it comes to complex social cues or deep-seated beliefs.
Actionable insights for the next time something goes viral
If you ever find yourself in the middle of a massive internet debate about perception, here is how to "break" your brain and see the other side:
- Change the tilt: If you're on a laptop, tilt the screen back or forward. Changing the viewing angle changes the contrast and can sometimes flip the colors for you.
- Shrink the image: Look at a tiny thumbnail. When the image is small, your brain stops trying to interpret the "lighting" of the scene and just looks at the raw pixels.
- Check the RGB values: If you really want to be "that person" in the group chat, open the image in a photo editor. Use the eyedropper tool. You’ll see that the "gold" pixels are actually shades of brown and mustard, and the "white" pixels are actually light blue.
- Isolate a patch: Cut a small hole in a piece of paper and hold it up to the screen so you can only see one small section of the fabric. Removing the context of the background usually reveals the true colors.
The dress is still the gold standard for viral illusions. It taught us that "seeing is believing" is a lie. Seeing is actually just your brain's best guess.
Next time you're certain you're right and someone else is wrong, just remember the Scotswoman’s dress. You might both be looking at the exact same thing and seeing two different worlds. That’s just being human.
