That dress and how we perceive colour

Leave a comment

Apparently this is the question that has divided the internet today. What colour is this dress?

That Dress

And the answer is…

 

 

 

 

 

It depends. Some people see it as white and gold and others blue and black. It depends on how you perceive the surrounding colours. People who perceive the photo as taken in poor light are likely to see the dress as white and  gold. Those who think the dress is taken in good light see it as blue and black.

It may be an optical illusion, but how many times have we been in a fabric shop and been unsure of a fabric’s colour. This is all down to something called colour constancy. Our colour perception ensures that the perceived colour of an object remains relatively constant under varying illumination conditions. For example, a green apple looks green to us at midday in white sunlight, and also at sunset, when the main illumination is red. Colour constancy is a process that allows our brains to recognize an object as being the same colour regardless of the amount of light reflecting from it at a given moment.

How many of us find ourselves wondering over to the window or door to get a better look at our fabric? (Whilst hoping the shop assistant doesn’t think we’re trying to make off with a bolt of fabric!)

Oh, and by the way, that dress in real life is actually blue and black. Take a look here if you don’t believe me!
