I’ve done my best to ignore the nonsense surrounding That Dress but I’ve lost patience with the abundance of stupidity that has been bought to the discussion. ISN’T IT AS OBVIOUS AS THE NOSE ON YOUR FACE? Neither the dress nor the photo of the dress are optical illusions. The dress was simply photographed under lighting conditions that gave rise to a photograph featuring colours that markedly differ from the actual colours of the dress as seen under regular lighting conditions, THEREFORE, the dress in the photo is different colours to the dress in reality. Here’s the big news; colours can be manipulated in photography! Amazing isn’t it? This manipulation can be done on a photo in computerized format using various computer applications, or the colours can be manipulated or altered before the photo is taken, by lighting of the scene to be photographed. In effect, the dress in the photo is a tint of the dress in reality. Why the confusion then? The confusion arose because the question “What colour is the dress?” requires clarification, but no one had the smarts to figure out that the question could be and was likely to be interpreted in two different ways, and thus the requirement for a clarification of the question was not identified. Some people, like myself, interpreted the question to mean “What colour is the dress in the photograph?”, and clearly it is a cold, mauvey-blue unsaturated colour and golden brown, no black, definitely no black, as anyone could see if they held an actually black item up against their computer screen while viewing the photo of the dress on their screen. Understandably, many other people interpreted the question as an invitation to guess, reason or theorize what the colour of the dress might be in reality, based on the way it appears in the photo. These people correctly and cleverly guessed or reasoned that the dress is blue and black. I do wonder about those who saw white and gold, but the question was a trick question, so I wouldn’t judge them.
There’s nothing I love more than a good optical illusion or perceptual anomaly, especially in real life situations, but I’m very sure this dress thing is not one of them. This problem appears to be one for the philosophers, not the psychologists or the scientists, but then again, I’m tempted to wonder whether there might be some measurable psychological or neurological or behavioural difference between those who naturally give an answer based on their immediate visual perception and those who naturally give an answer based on their own interpretation of their visual perceptions. I suspect that the difference might be interesting and meaningful. I’ll bet the former are less prone to most genuine visual illusions.
Postscript March 5th 2015
I’d like to add another point to this post. From what I’ve read this entire dress discussion had it’s origin in the non-scientific world of social media “guys please help me – is this dress white and gold, or blue and black? Me and my friends can’t agree and we are freaking the fuck out”. This young lady who does not appear to be a scientist or a psychologist discovered a very interesting perceptual anomaly phenomenon thing that has sparked huge discussion, including discussion by and among scientists, and the story has been reported in at least one international science magazine. I find it interesting that this dress meme didn’t come from the world of science. Would it have been ignored or have failed to “go viral” if a scientist had discovered The Dress? Does this say something about the sociology of this meme, or is it more the case that a non-scientist has discovered a phenomenon that is more interesting (in regard to the way it has identified puzzlingly polarized responses in large numbers of people) than anything that scientists or academics have discovered recently. Is this an example of non-scientists (not even citizen scientists) making a greater contribution to the science of colour perception than the actual scientists who are supposed to be right on top of this stuff? I know that researchers and others have identified many different types of visual illusions that are supposed to trick most or all people, but I’m not aware of a visual stimuli that polarizes viewers the way The Dress does. Am I simply ignorant? As I have written before, I believe that science is too important to leave it to the scientists.
