Munker illusion

The Munker illusion involves colored strips arranged over a pattern, causing observers to perceive existing colors differently. When colored bars are placed over a grid with black and white squares, the colors in the bars seem to shift or change depending on the background patterns, even though their actual colors stay the same. This illusion illustrates how our visual perception is influenced by surrounding colors and patterns, revealing that what we see isn't just about the object itself but also how it interacts with its context. Essentially, it demonstrates how background and adjacent colors can trick our brain into perceiving color differences.
