Remember that dress the mother of a bride wore in Scotland that launched a million disagreements in 2015, with some people swearing it was white and gold while others bet it was blue and black? Depending on what kind of light you thought the dress was photographed in, your brain made the necessary adjustments and informed you of the colour of the dress. “Shadows are blue, so we mentally subtract the blue light in order to view the image, which then appears in bright colours -- gold and white,” Wallisch explained in a release. “This suggests that whatever kind of light one is typically exposed to influences how one perceives colour,” Wallisch said. Larks are more likely to see the dress as white and gold, while night people as blue and black.
