Chromatic Adaptation

Have you ever entered a movie theater on a sunny afternoon? The room probably appeared completely dark but as your visual system adjusted to the reduced level of light you were able to see better after a few moments. 

This "adaptation mechanism" allows our eyes to recover from an oversensitivity to a particular stimuli. "Chromatic adaptation" occurs when our eyes adjust to certain color stimuli. Follow the instructions below and see how the visual system responds to a color overload. 

Instructions: Fixate upon the black spot in between the uniform cyan and yellow areas for about 30 seconds. Then scroll down and shift your gaze to the black spot in the 2nd image. Note that the image of the seaplane appears approximately uniform after this adaptation.

 Stare at the dot for 30 seconds, then scroll down
