The answer is we don't know.
The brain makes interpretations of colour, just like in the grey square demonstration in the gif posted earlier.
It is one theory that some people have greater optical reception of certain parts of the colour spectrum which may explain why some people see the dress as different colours than the blue / black that it really is.
On the perception front, it comes down to the assumptions that the brain makes about what the eyes detect. That's why different people see it as white gold and others see it as blue black.
This colour perception problem is something that scientists the neuroscience and optometry fields have been debating for years and nobody is any closer to fully understanding it.
