Part One:

The checker shadow illusion is a check board which is color light grey and dark grey in different squares and green cylinder object that is place on right side corner that cast a shadow over the middle of the board diagonally. In addition, there are two square labeled “A” which is located at the top corner edge outside of the shadow of the cylinder and the square label “B” is located at the center of the board and under the shadow of the cylinder. When I view the illusion and asked myself which one is darker I would immediately say the square label “A” is darker.

In this illusion, the cylinder causing the shadow makes the brain perceives the color to be lighter that is actually is and causing us to see it that way.

Part Two:

The illusion that I have chosen I believe is the one that will continue to fool me no matter how much I study it. I came back an hour later and viewed illusion.
