A British woman posted a picture of a dress that has people asking ‘what color is this dress’? When you look at it, it looks blue and black, but most people think its white and gold.

Taylor Swift weighed in saying she thought it was blue and black, I think it is blue and black and guess what, the designer of the dress confirms it is blue and black. But more than half of the 28 million people weighing in on the color think its white and gold.

Why do so many see the color so differently? It has to do with how our eyes perceive color. It has to do with lines of tissue in the back of your eye called ‘cell cones’. They sense color and if you have too few you will see white in the dress, if you have many, you will see blue.

Look at the dress, what color do you think it is?
