lol not this!
it's blue and black.
you have to take into account the entire picture instead of just sampling or cropping parts of it. I've seen too may 'explanations' where they're measuring the RGB values of points of the image - that's utterly irrelevent. it's obvious that the blacks appear to have a golden cast to them but that's not the colour of the dress it's just the colour of the data.
the hints are as follows:
-The whole photo is blown-out, over exposed. the blacks [of the image] are already quite lifted.
-Digital cameras without IR filters will give a tint to synthetic black fabrics; this is a well known fact. the tint is often magenta / red or orange - you will see this a lot if you take a photo of someone in a dress-suit - the lapel will often be red looking in the photograph. CCTV cameras also have a very strong effect like this.
-There's just enough green in a point-sample to make it read as being gold.
-When a [cheap] camera is over-exposed like this the blacks hardly ever remain neutral; they nearly always lean towards one channel; often red.
-The warm light in the background only adds to all of this.
-I can't believe there is a debate over this, and I can't believ I'm contributing to it!
