Adelson’s checker shadow illusion: Squares A and B have the same brightness, but due to the cylinder’s shadow and the checkerboard pattern, square B appears lighter.
The yellow and brown squares on the faces of the cube are the same color. This can be easily verified using the eyedropper tool or by overlaying a mask.
