optics

Two great optical illusions demonstrating how, due to the limitation of our vision system, our brain ‘averages’ the information it receives and fills in for us the missing pieces.

This picture of brown balls by David Novick! The Munker-White illusion.

“A three-colour confetti illusion with spheres, which appear to be yellowish, reddish, and purpleish but in fact have exactly the same light-brown base colour (RGB 255,188,144). Shrinking the image increases the effect.”

David Novick

This black-and-white (grayscale) photo (by “Chuwa (Francis)”) has been modified by artist Øyvind Kolås. Colored lines were printed across parts of the image. Our brain fills in the missing information and present it to us as if there were uniformly colored shapes. (except for the red, which doesn’t work for me that well)

The red works however better when the image is smaller.

“An over-saturated coloured grid overlaid on a grayscale image causes the grayscale cells to be perceived as having colour, “

Øyvind Kolås
