Colour Perception - when seeing is not believing

Colour perception

Recently at a presentation, I used this image to demonstrate that our perception of tone and colour is easily fooled.  The brown square at the centre of the top face and the orange square in the centre of the face at left are exactly the same.  To check this for yourself, download the image and open in Photoshop.  Then, using the colour picker, sample each square to prove they are the same.
