We See Colors Differently in Winter and Summer

"Scientists at the University of York have shed new light on how humans process colour - revealing that we see things differently in winter compared with summer," writes Medical News Today. "The researchers examined how our colour perception changes between seasons and in particular how we process the colour known as unique yellow. Humans identify four unique hues - blue, green, yellow and red - that do not appear to contain mixtures of other colours. Unique yellow is particularly interesting to scientists as it is stable across large populations - everyone agrees what unique yellow looks like despite the fact that people's eyes are often very different. The researchers in the Department of Psychology wanted to discover why this colour is so stable and what factors might make it change. They thought that unique yellow might depend not on the biology of the eye but on the colour of the natural world." Read more.
