Chromatic Adaptation

Look at the cute little boy he's shown in two different colors, right ? Now gaze at the plus sign below between the yellow and blue for 20 seconds. Then look at the plus sign on the little boy's nose. The image is looking normal now! Isn't it incredible? This phenomenon is called chromatic adaptation. Your eyes adjust themselves to the overload of colors. When you look at the right, your eyes are still filtering out the cyan and yellow. Will last for a while.
