This is how it works.
you better stare at the dot in the centre of the false-colour image for around 30 seconds.
In other words, the false-colour image acts like a kind of negative for the scene.

The trick works due to an effect known as afterimage.
One question stood about among the rest because it was asked again and again.
People really care about it.
The question is: Is the colour you see the same as the colour I see?
Otherwise, how do I know that my interpretation is right or whether it means anything at all?
Surely a red apple is red, and thats the end of it.
But how do you check?
And then along came The Dress.
