Unravelling the effects of coloured environments and coloured lightsThe literature on the psychological and emotional effects of colour is both vast and confusing, with many contradictory findings. For example, on the one hand we are told that blue is a calming colour and a suitable colour for a bedroom; yet on the other hand we are told that blue light has an alerting effect and exposure to blue light in the hours before sleep can be disruptive. How can these seemingly contradictory effects be reconciled? In this talk, Stephen Westland will present findings from several studies at the University of Leeds to develop a framework that tries to make sense of the different effects that colour has. In particular, the effects of coloured environments and coloured lights will be compared.
