Akiyoshi Kitaoka, a psychology professor at Ritsumeikan University in Kyoto, Japan, loves torturing the internet by posting unsettling optical illusions on his Twitter account. Using his deep knowledge of how the brain processes images, he creates illusions that force you to accept the reality that everything you perceive in life is just your mind lying to itself. It's a lot of fun.

In the last week, he's gone viral with a truly unnerving image of some delicious strawberries. Take a look.

As the professor points out, there isn't a single red pixel in that image. The strawberries are entirely represented in shades of gray. You only perceives them as red because of color constancy, a phenomenon in which the brain automatically corrects colors based on the surrounding ones, so that you'll be able to judge colors accurately even under unusual lighting.

Still unsure? Still tempted to take the blue bill? Twitter user @carsonmell isolated the "red" strawberry colors, just to shatter your world.

It's the same phenomenon that caused people to see The Dress differently. So it might be time to apologize to all the family members you wrote out of your will because they insisted it was black and gold.

Meanwhile, Professor Kitaoka is enjoying his viral fame.

Here are some more of his illusions for you to enjoy. They're a lighthearted way to remind yourself that your brain is just a flimsy hunk of meat.
