I saw that and wondered what was going on. As far as I'm concerned it's a
case of color blindness. I downloaded the image and I see white and gold.
Looking at the histogram I can see why. The histogram says I should be
seeing white and I am except for a small blue tint due to the dress being
in shade.
When I adjusted the image to drastically reduce the red component and
slightly reduce the green component (a common form of color blindness) then
I see that the white has turned blue and the gold has turned black.
But 25% is a pretty large number for color blindness although it does vary
significantly in different populations because of the genetic component.
Wiki says:
Color blindness affects a significant number of people, although exact
proportions vary among groups. In Australia, for example, it occurs in
about 8 percent of males and only about 0.4 percent of females. Isolated
communities with a restricted gene pool sometimes produce high proportions
of color blindness, including the less usual types. Examples include rural
Finland, Hungary, and some of the Scottish islands. In the United States,
about 7 percent of the male population—or about 10.5 million men—and 0.4
percent of the female population either cannot distinguish red from green,
or see red and green differently from how others do (Howard Hughes Medical
Institute, 2006). More than 95 percent of all variations in human color
vision involve the red and green receptors in male eyes. It is very rare
for males or females to be "blind" to the blue end of the spectrum.

Here is the votes in our house -
Blue and Black - me, my wife and our young son.
White and gold - our elder son.
One survey says 75% see white/gold and 25% see blue/black, I never
thought this would happen.
