This is why when painting you want to develop your entire canvas from simple to complex, and not tightly finish one little area before moving on – so that every color is in context all along.

Its not really an "illusion" at all. Its about context. Its surroundings, that give perceived value. Our brains are always interpreting what our eyes see, making adjustments Here's another video showing similar demonstrations of this. http://www.ted.com/talks/beau_lotto_optical_illusions_show_how_we_see.html

Gary is right, it’s a well-known “trick” to use gradients in such simultaneous contrast demonstrations.
For those who dig such things, I have made various Flash-animated illusions here: http://www.klausnordby.com/ego/illusions.html

The diamonds are all gradients, with the tops lighter than the bottoms. This makes the diamonds on top appear darker, since the bottom of the top diamonds is darker than the top of the lower diamonds.

I would be very glad to have an explanation of this “illusion”.
