Seeing colour in a contemporary light
21 October 2015
Colours are not physical things but the result of a process that starts in the eye and continues in the brain. The limits of colour constancy, when the colours of objects appears the same under different lights - from daylight to LED light, will be explored by a leading visual neuroscientist at a free University of Bristol public lecture next week [Thursday 29 October].
Anya Hurlbert, Professor of Visual Neuroscience and Director of the Centre for Translational Systems Neuroscience at Newcastle University, will give this year’s annual Richard Gregory Memorial Lecture, held in memory of the great interdisciplinary thinker and University of Bristol academic, Professor Richard Gregory.
The lecture, entitled Seeing colour in a contemporary light: from daylight to LED light, via old masters and a dress, will take place on Thursday 29 October at 6 pm in Lecture Room 1, School of Chemistry, Cantock’s Close, Bristol. The event is organised by the Bristol Vision Institute (BVI).
Professor Hurlbert’s research is in understanding the human brain, through understanding the human visual system. She focusses on colour vision and its role in everyday visual and cognitive tasks in normal development and ageing as well as in developmental disorders such as autism. She has particular research interests in applied areas such as digital imaging and novel lighting technologies. Her talk will illustrate the limits of colour constancy by describing experiments using tuneable multi-channel LED light sources, carried out both in the lab and in public installations.
