        \_ Amazing.  Even after measuring the shade of grey with Photoshop, I
           still find it hard to believe the two checks are of the same gray.
           \_ yeah I had to do that also, I cut and pasted them side by side.
        \_ Uhm... I simply blocked out the rest of the screen with some paper.
           I don't see how they're the same.
           \_ The "A" and the "B" letters are still deceiving your brain.
              \_ I blocked that out too.  Maybe I'm just blind.
                 \_ maybe this animated GIF will help.
