I see a photo with tons of noise. In any case, I so see blue(ish) and gold-green-black (likely a result of the noise). I don’t see how 73% see white. I opened the pic into photoshop and the eyedropper on the shoulder reads R:103 G:104 B:134. So whether this is a white dress with really bad colour balance or it really is blue, for all intents and purposes, it’s blue. Unless the poster is messing with people’s minds and switching up the pic because I notice one person first saw white and now blue.
What confuses me most is why you, CC, see white. I don’t want to say I don’t believe you but I also trust my own eyes. On my monitor and my wife’s laptop, we both see blue. By the way, the “original” dress does appear to be a nice cream colour and far from blue.
I don’t know what’s going on here.
On a side note, not to imply anyone has any colour deficiencies, (1 out of us 12 men have some deficiency), it’s always fun to take the Farnsworth Munsell test..http://xritephoto.com/ph_toolframe.aspx?action=coloriq
Lucky me I rank 0. Of course it helps immensely to take the test with a properly set up monitor.
