That one I see black and blue too but the shot that the confusion is about is differently balanced and is actually blue and brown but all I read is that there are only two possibilities people see.
I heard others who saw brown too
Well, I'll be happy with the latest idea about what's going on, but blimey, it's still so much fun watching it change color, while staring at it :-D
Just been with some girlfriends and one had different images which, after looking at those, the 2 girls who only had seen w/g, saw it b/b. I tried some simple red-green blindness test on them, but they could see it just fine.
