We see objects because light is reflected. Human eyes try to compensate for the chromatic bias of daylight colour. Human beings evolved to see in daylight, but daylight changes the colour of everything we see. But why would your eyes lie to you like this? What’s happening with #TheDress is that your eye is either discounting the blue so you’re seeing white and gold, or discounting the gold so your eye sees blue and black.
Colour illusions are images where the object’s surrounding colours trick the eye into incorrectly interpreting the colour.
You may have gathered this by now, but what we are experiencing is really a colour illusion. But it is too early to say whether the difference is genetic, as with tongue rolling ability, or something affected by learning and personality such as being a night-owl or one’s particular sensitivity to context in perception, as I and fellow Sackler colleague Acer Chang speculate.” Here’s the science behind #TheDress colour illusion “It is as if there is a perceptual equivalent of those who can roll their tongues and those who can’t. Photograph: Ĭhrisley said: “Another striking thing about the dress illusion is that it is quite unlike the checked shadow illusion, in that not all people experience it, and those that do often do so differently. Cover the surrounding squares and you’ll see they are in fact the same colour. Squares A, B and C appear to be different shades of brown. People who have changed luminance in Photoshop may not be fooled by it.” “This has yet to be proven, but given what we know of the brain, and it’s a good guess, is that someone who is used to manipulating images and white balance might be able to perceive the true dress colour in a wider range of contexts and ignore context, whereas others can be easily manipulated. Some people see just what’s in front of them and some people are affected much more by the context. “Some suffer more than others due to how people factor in context in order to construct a colour experience. We use the context to inform our colour experiences. Photograph: īoth surfaces are grey, right? But how?! Why?!Ĭhrisley said: “Which colour we see isn’t just a matter of the light coming into eyes, it’s the inferences that caused that input. The image below, tweeted by demonstrates that even though the right-hand side of each image is the same, in the context of the two different left halves, the right is interpreted as being either white and gold, or blue and black. The internet is now made up by people firmly in two camps: the white and gold, and the blue and black – with each thinking the other is completely wrong.īut Ron Chrisley, director of the Centre for Research in Cognitive Science at the University of Sussex, believes that the problem mainly lies in the fact that everyone has forgotten we are dealing with an illusion.Ĭhrisley said: “The first step in reaching a truce in the dress war is to construct a demonstration that can show to the white-and-gold crowd how the very same dress can also look blue and black under different conditions.” PS it's OBVIOUSLY BLUE AND BLACK- Taylor Swift February 27, 2015 I don't understand this odd dress debate and I feel like it's a trick somehow.
