^Yes, the squares A and B are EXACTLY the same colour. The human visual system does so much pre-processing that it recognises that the cylinder is casting a “shadow”, and edits the perceived image such that you see a colour much nearer the colour that would have been there, were it not for the shadow.




^This one is my favourite

3Dejong let out a deep sigh at PS's naivite. He had not meant to show an illusion, only a cutting remark.
