International SymposiumAIC 2020, "Natural colours - Digital colours" on 20, 26 and 27 November 2020 with Laure Bonnaud-Ponticelli

The French Colour Centre (CFC) is organising an international symposium on the theme "Natural colours - Digital colours" on 20, 26 and 27 November 2020. Initially planned at the Palais des Papes in Avignon, this conference will be held in video.

This symposium is part of the multidisciplinary activity (color industries, research, teaching, art, crafts...) of the International Association of Color (AIC).

Laure Bonnaud-Ponticelli, MNHN/BOREA Professor, is a guest speaker and will share on “Natural colours of living environment” on Thursday, November 26.

Abstract:

Living organisms, plants and animals, have specific colours resulting from pigments and structural colours assembling. Animals do not synthetize carotenoids or chlorophylle but are able, by plant feeding, to re-use them. Colours have been selected during evolution as they confer to organisms an adaptive advantage in a specific environment. Acclimatization, short adaption by temporary changes are observed: passive as in a fruit maturation or active as in change pattern of an octopus. Colours have crucial role in different life traits: in reproduction, camouflage, protection, communication. Nevertheless, the function of some colours remain still a mystery for our human vision (and understanding). Plant and animals’ natural pigments are used from antiquity essentially for fabrics dying or artistic purpose.  They have now their synthetic forms, cheaper to produce and are used for numerous food industry applications.
