Kanizsa's Triangle and Marketing 101

This figure above was introduced by Gaetano Kanizsa, an Italian psychologist. Everyone sees a white triangle in front of the three black disks and inverted triangle. However, the white triangle actually does not exist. The contours of this triangle are illusory contours created by your brain. Note that the illusory triangle looks brighter than the background. This is a result of brightness contrast caused by the black disks being partially covered by the corners of the illusory triangle.

Remove the black circles and the white triangle vanishes.

We actually see the Kanizsa Triangle Optical Illusion often in everyday life. We see a "Kanizsa Girl", we all see a girl where no girl actually exists.
