A = B?

Are squares A and B the same color? In fact, they are, as the below illustration proves. This is an example of the same color illusion, created by MIT professor Edward Adelson. A description of how the illusion works can be found here. I verified that the "colors" were the same by using a Firefox add-on called ColorZilla; in hexidecimal format, the code for this particular color of gray is #787878.
