Vien Cheung, academic at the University of Leeds, UK
Vien Cheung, an academic at the University of Leeds in the UK, has authored more than 100 refereed publications in the areas of colour vision, colour science, colour imaging and colour design. Her achievements have been recognised both in the UK and internationally. Most recently, she was awarded a Gold Medal from the Society of Dyers and Colourists (2023) in recognition of her prolonged and outstanding contributions to international colour research, education and its publication. Her ethos on integrity and diversity takes her to explore how colour can be used as a vehicle to shift our ‘black and white’ judgements into a more variegated and expansive perception of the world. Vien is also active in charitable and educational colour organisations including the International Colour Association and the Colour Group (Great Britain) in which she is a Past President and the Chairman respectively.
Title and Abstract
Title: Colour association: rational or groundless?
Abstract:
It has widely been agreed the strong association of colours with certain psychological or mental states. For example, often colours are expressed as being warm (e.g. red, orange), cool (e.g. green, blue), aggressive (e.g. red) or calm (e.g. blue). Is such strong association driven by our innate biological factors, accumulated through our learned life experiences or simply a part of the rules of the universe? This talk will discuss the origin of the fundamental colours, and their representations, of various historical philosophical theories around the world; in particular, an analysis on the comprehensive Chinese five-essence theory will be presented may shed light on the answer.

Title: A gamut boundary test chart for extended colour gamut reproduction
Abstract: A test chart is defined for 7-colour printing. The chart is based on one already in use for four-colour process printing, but with a flexible mechanism for adding up to three further colorants used in extended colour gamut printing The chart can readily be used to determine a gamut boundary description consisting of vertex list and face list, The resulting gamut boundary description can in turn be used in the applications of gamut mapping, gamut analysis and gamut visualization.
