Yes, very, very cool, thanks for linking to that article!! When I first saw the picture the blue was much, much more pale. Now it looks like a medium periwinkle to me, and I cannot for the life of me get my brain to "see" that pale blue again! SO interesting.
However, I'm still baffled that some folks are describing the blue as a deep indigo (like the stock color of the dress). This, I'm starting to think, is a product of people using the same word to describe different things. To me the stock dress is a royal blue or bright indigo. My DH would likely describe that same color as "dark blue".
Crayola 64, anyone?
