What I wonder is that there is clearly black and white cloth visible in the leftmost side of the picture. There is a reference, same lighting, exactly same time. 
Anyway, the dress manufacturer has confirmed it's black/blue.

^^^^^^^^^^ This
 

This is interesting too:

There's a test with a circle of green squares at the end, you have to spot the one that's slightly different. I am proud to say I got it, but it isn't immediately apparent.

Black and red. 
All the rest is irrelevant. 
:P

Welp...I have Red/Green color blindness but I saw Periwinkle and Gray/Black.

PS: I just love those "fool your brain" thingys:-)

I found the test very easy (the "different" square had just a touch of yellow in it).  That said, I also found the article very interesting!  I'm a bit surprised that Homer described violet but not blue though, I was thinking it may have had something to do with wavelengths, but I guess not.
 
It's fairly well known that the human eye can distinguish far more variations of green than any other color which is why night-vision goggles use green light.
 
Ironically, my favorite color is blue. 
 
(Heck my trance and anything goes band name has been bluezero since the 70's and my Classic Rock band name has been Sky Blue Voodoo since the 80's!)
 
That said, I'm about to make a website that Rain would like since it features black and red.

She has no arms, nice, very nice figure. But no arms

You are always attracted to women who are out the norm,,
 
and that ALWAYS gets you in trouble....
 
remember the secluded plot in the woods/divorce lawyer/tractor....

I'd seen this a lot last Friday and came to the conclusion that it's clearly blue and black. But oddly enough, every time I refresh this page and only see the top half of the original image it sure looks white and gold! Haha

This just in...Humans are no longer qualified to evaluate objective facts and render a decision. From now on, all decisions will be made by trees. It is generally believed by most conifers that this is the most logical course of action. Trees typically cause fewer wars (with the obvious exception of the Oaks and the Maples), post fewer embarrassing videos on Facebook, live longer, produce more oxygen, and are the undisputed masters of the Knock Knock joke. When asked for a comment, a Redwood responded that humans will be put to work falling in the forest to see if they make noise. 

Don't you have a book to write? 
 

my incredulous response is why is there so much flap made over the damn thing?
 
who cares???
 
are we so bored looking for bread and circuses that anything draws us, mothlike, to a flame....
 
sure, you can offer some scientific response to human brain color recognition, hardware discussions about rgb monitor palates, and dress colors ecen
 
who cares?
