Debate rages over color of dress photographed in rare light

This photo of a dress has caused an internet uproar: Is it blue and black, or white and gold?

So far, according to Buzzfeed, about three-quarters of respondents see white and gold.

But why are people seeing such wildly different colors? First off, it's not monitor settings.

It's probably not about the cells in your eyes.

Our retinas have specialized cells called rods, which are used for night vision, and cones, which deal with color. But these cells are probably not the source of the dress dilemma.

Cones come in three types: red, blue, and green. And each of us has very different ratios of these types. But the different ratios "don't seem to have a big impact on our color vision," said Cedar Riener, associate professor of psychology at Randolph-Macon College. "I could have a 5-1 ratio of red to green cones, and you could have 2-1, and we could both have similar color sensitivity."
