These Strawberries May Look Reddish, But This Image Contains No Red Pixels

Certainly you remember when "the dress" was the most unavoidable thing on the internet—it was the maddening optical illusion that had people scratching their heads to decide which colors were actually on one dress. In February 2017, the "not-red strawberries" happened. Akiyoshi Kitaoka, a professor of psychology at Ritsumeikan University in Japan with an optical illusions speciality, removed all the red pixels from a photo of strawberries on a tart.

Learn more about that science in the video below.
