Abstract

We propose to use current spectrographic techniques for detecting colourants in cultural items in a semi-quantitative way, by systematically utilising the notions of colour term, basic colour term (BCT), and by sampling the coloured areas of each BCT. Given for example two manuscripts (MSS), criteria for sampling the areas of the illuminations of a given BCT, and the detected colourants of those areas, it is possible to estimate a degree of colourant difference. Further, a unique identifier of the item colourants is proposed. For achieving this aim we discuss some steps of the analytical procedure, and borrow from ecology three homologous concepts for detecting colourants, i.e.: for a given BCT, the colourant richness, the colourant abundance distribution, and the evenness of this distribution. Further, we explore a procedure, the input of which is a generic picture, and the output is a map of the same object giving the BCTs distribution.
