A classy illusion

I read this on bau and dineshs blog: http://bawandinesh.blogspot.com


The Squares marked A and B are exactly the same colour!!!

To check this out, just copy paste the image into any image software(GIMP,KolourPaint or MSPaint)… then cut paste a tiny part of square A into a new window, and then copy paste a tiny part of square B into another window… check out both the colours, you will see that amazingly, unbelievably they are the same!!!

Seeing is believing ?Not quite , huh?
