20 Mind-Bending Optical Illusions To Test Your Perception

It’s pretty crazy to think that we can only see things due to the light that’s reflected off them, but that also means that our eyes and brains are vulnerable to being tricked into seeing things that aren’t actually there. These optical illusions will leave you questioning everything!

You should still be able to see color when the image fades to black and white. That's because your brain will automatically fill colors in for you if it thinks that they should be there.

Are the lines in the image below all parallel to each other, or are they sloping? Take your time before making your mind up.

Answer: While the lines do appear to slope, they're actually all parallel to each other. The brain fills in the gray lines between the black and white squares, meaning that they can be quite hard to see at first.
