It occurred to me today that the Checker Shadow Optical Illusion that I presented here could have been better presented if it fit my blogs color scheme so I decided to modify the original. I gave it a black background and changed the light source.
The bottom line is still the same. Square A and Square B below are the exact same color. Hard to believe isn't it?
I look at this and find it hard to believe. But I used the extension in Firefox called colorzilla which provides you with an eyedropper tool. I checked both of squares and sure enough the RGB values of the grays in both square A and square B are 135-135-135.

If you don't believe it print the image and cut out both squares then hold them next to each other. I have done exactly that. I know they are the same color, but my eyes refuse to allow me to see it by just looking at the picture. Try and convince yourself that they are the same color. I know it is true but I don't see it as being true.

Wow that is incredible!!! I still can't see it... but I believe it. Weird!
I had to test it with the Firefox extension so I know they are the same colour but I can't see it and if it were not for my test I would not belive it.
o my! it's true!
cool blog here... love the illusions.
To my eyes they visually appear to be the same color. I must be in the small minority.
I can look at this in a similar "non focus" way like you have to when looking at "magic eye" pictures and then the colours match.
