Optical Illusion - Shades of Difference

This video demonstrates that the human eye (and the visual cortex of human brain) are better at detecting edges and contrasts than they are at determining actual shades of colors.  There is a discussion thread about this illusion at Reddit.

This one is not based on the Cornsweet-principle. This is just graduations like I had to make when I had to learn to mix colours in paint-restauring class.

Dear lady,
The same colour is not present. Would it be the same colour, you would be able to take out the 2 middle colours and see no difference. The minimal difference in colous causes the brain to perceive the difference that is there as a difference in light or shadow. Therein lies the illusion.
