either use the "dropper" to check the values of the RGB
or just do a cut and paste,
cut out pieces of A & B and put them together...

Very, very interesting... this is truly one of the most amazing optical illusion figures I've ever seen. So much for our eyes' built-in color balance/curves functions.... :what:
i just had to do it for myself... still have trouble believing my eyes when i dragged square A next to B in PS... :what:
Nice. 
Another way to see that they are the same without using photoshop is to use your hand with your fingers curled up into a tube, put it over the A square to isolate and look at it. Do the same for the B square.

Wow, at first I thought it was a typo comparing 1 and 2 (or A and B).
Truly amazing!
Do you know of any website that have more of these optical illusions?
Thx,

cut two holes for the two spot on a paper....then mask it over the scren/monitor.....can see its the same
no leh... is it my monitor not calibrated properly or what.... even if i cover the squares individually, they still look diff colour leh....
also, if use PS, it indicates that they squares have diff amount of RGB or CMYK leh...

tsk tsk tsk..........RL, this image is copyrighted - u should have at least credited the university professor or link the image from his website instead of hosting it from your own site. His original site also contain the explanation for the illusion
Here's the original link.
The explanation for the illusion can be found here
anyway this image was brought up in 2 separate threads (one of which unfortunately can no longer be viewed ) in the Photo.net forums last month.
Here's one of them:

It's interesting to note the different cultures of the 2 forums - in Photo.net, both threads spawn extensive discussions in relation to the different ways of metering and deriving correct exposures in light of the deception contained in the image.
Over here in CS, the topic is listed under Banal Talk, and the discussion is more "fun" and a tad less serious, with no attempt to relate the illusion to actual photography
