Do you remember the black-blue – white-gold dress that once left internet users completely puzzled?

The dress sparked a massive debate in the online community, revolving around the actual colors it represented. Some insisted it was black and blue, while others claimed it was white and gold, with no one having any issues with their vision. Although it was later proven that the black-blue team was correct, the debate surrounding the dress’s colors remained hot even into 2021.
But did you know, internet users didn’t just go crazy over this dress? There have been many images that left people feeling confused because they looked one way but were not what they seemed. The images below are clear examples.
1. Is This a Color Photo?

Actually, no! It’s a black-and-white photo with colorful lines interspersed throughout. The issue is just that, but your brain will automatically fill in the gaps with corresponding colors, making you perceive it as a color photo.
2. Photoshop, Right?

This image has been causing a stir in the online community recently. It first appeared on the Twitter of a user named Holly McKee, taken as she passed by a children’s clothing booth in a shopping mall.
At first glance, this image does indeed look like it has been edited to remove color, or that the camera somehow erased color from part of the frame. But no, the camera was functioning normally, and no one edited anything because that was the actual color. It’s simply a clothing section devoid of any bright colors, intentionally arranged by the store to leave us confused.

3. Being Followed by a Cat on Paper
In this picture, there’s a photo searching for a lost cat, but no matter which angle you look at it, the cat in the image seems to be watching us, doesn’t it?
The reason is that the paper is stuck to a non-flat surface, which causes the image to appear differently depending on your perspective.
4. A Helicopter Flying with Blades Not Spinning
Looking at this helicopter, what do you think? A new magic trick, where its blades aren’t spinning at all yet it manages to fly?
If you don’t believe it, check out the video below.
The helicopter flies without the blades needing to spin.
Do you find this illusion strange? In fact, it’s genuinely an “illusion”, but it’s a visual illusion. This phenomenon occurs because the speed of the blades matches the frame rate of the camera, which creates the effect of the blades appearing to be stationary while still allowing the helicopter to fly.
5. Kendall Jenner’s Invisible Leg

This image was posted on the Instagram of Instylemagazine, featuring three famous ladies in the Western entertainment industry: Hailey Baldwin (now Mrs. Justin Bieber), Kylie, and Kendall Jenner. However, what caught the internet’s attention was not the three figures but Kendall’s missing leg.
After some time of searching, internet users finally found that leg. It was simply under her beautiful yellow dress!
If you look closely, you can see it. She had turned her knee to the right, propped her right leg up, while leaning toward the camera to stand out more. That’s the reason for the problematic visual illusion.
