I'm not at all sure that we can trust what we're seeing to be the same
thing. If I load your link below
<http://www.bbc.com/news/uk-scotland-highlands-islands-31656935> into
Photoshop and sample the colors of each the readout tells me that my
eyes are seeing exactly what I should be seeing. The image at left
shows a white dress with a blue cast (roughly R=130, G=145, B=190)
whereas the image at right shows a clearly blue dress (roughly R=60,
G=70, B= 190).
So, if these are the same dress (and I assume they are) it's not me
that's confused, it's the white balance of the camera and any follow on
processing that has taken place. I will also note that the dress at
left in the same link is the same photo I had seen originally but from a
different source. This version I still interpret as probably white but
its blue cast is decidedly darker than the "same" image I saw from the
other source.
No doubt our visual systems are different but I'm not going to get
worked up about a clearly non-scientific color presentation.

It is not related to colour blindness, the percentage of colour blind
peoples are much less than that.
The colours seem not marginal, the one who see white and gold is very
firm about it and it is the same the other way round.
Correct the white balance is not the point, the question is why we see
them differently even on the same monitor.

Just seems to me that if the dress had been photographed correctly
(correct
exposure and white balance) there may have been far less dispute about
the
colour. I can't dispute the fact that the small proportion of people
with
some form of colour blindness would interpret the colours differently to
those without.

Here is an explanation of why we see differently.

And these may help to confirm the actual color of the dress.
